Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015312, here are decompositions:

  • 3 + 1015309 = 1015312
  • 113 + 1015199 = 1015312
  • 149 + 1015163 = 1015312
  • 173 + 1015139 = 1015312
  • 239 + 1015073 = 1015312
  • 251 + 1015061 = 1015312
  • 269 + 1015043 = 1015312
  • 359 + 1014953 = 1015312

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 5312 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5312-10-01 (MMDYYYY (US, single-digit day))
  • 5312-01-10 (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 1,015,312 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 1015312 first appears in π at position 42,863 of the decimal expansion (the 42,863ordinal-suffix:rd 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.
