Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658812, here are decompositions:

  • 73 + 8658739 = 8658812
  • 103 + 8658709 = 8658812
  • 139 + 8658673 = 8658812
  • 193 + 8658619 = 8658812
  • 199 + 8658613 = 8658812
  • 223 + 8658589 = 8658812
  • 229 + 8658583 = 8658812
  • 241 + 8658571 = 8658812

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 8,658,812 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 8658812 first appears in π at position 851,500 of the decimal expansion (the 851,500ordinal-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.
