Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015258, here are decompositions:

  • 59 + 1015199 = 1015258
  • 131 + 1015127 = 1015258
  • 191 + 1015067 = 1015258
  • 197 + 1015061 = 1015258
  • 269 + 1014989 = 1015258
  • 317 + 1014941 = 1015258
  • 389 + 1014869 = 1015258
  • 479 + 1014779 = 1015258

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 1, 5258 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5258-10-01 (MMDYYYY (US, single-digit day))
  • 5258-01-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,015,258 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1015258 first appears in π at position 550,475 of the decimal expansion (the 550,475ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
