Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015178, here are decompositions:

  • 7 + 1015171 = 1015178
  • 19 + 1015159 = 1015178
  • 97 + 1015081 = 1015178
  • 127 + 1015051 = 1015178
  • 139 + 1015039 = 1015178
  • 271 + 1014907 = 1015178
  • 457 + 1014721 = 1015178
  • 547 + 1014631 = 1015178

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 5178 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5178-10-01 (MMDYYYY (US, single-digit day))
  • 5178-01-10 (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 1,015,178 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 1015178 first appears in π at position 546,259 of the decimal expansion (the 546,259ordinal-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.
