Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685700, here are decompositions:

  • 17 + 8685683 = 8685700
  • 41 + 8685659 = 8685700
  • 47 + 8685653 = 8685700
  • 71 + 8685629 = 8685700
  • 131 + 8685569 = 8685700
  • 227 + 8685473 = 8685700
  • 293 + 8685407 = 8685700
  • 389 + 8685311 = 8685700

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 8,685,700 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 8685700 first appears in π at position 290,215 of the decimal expansion (the 290,215ordinal-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.
