Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705312, here are decompositions:

  • 13 + 8705299 = 8705312
  • 43 + 8705269 = 8705312
  • 163 + 8705149 = 8705312
  • 271 + 8705041 = 8705312
  • 283 + 8705029 = 8705312
  • 331 + 8704981 = 8705312
  • 409 + 8704903 = 8705312
  • 601 + 8704711 = 8705312

Showing the first eight; more decompositions exist.

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 8,705,312 and was likely granted around 2014.

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

Position in π

The digit sequence 8705312 first appears in π at position 894,950 of the decimal expansion (the 894,950ordinal-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.
