Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685558, here are decompositions:

  • 19 + 8685539 = 8685558
  • 41 + 8685517 = 8685558
  • 149 + 8685409 = 8685558
  • 151 + 8685407 = 8685558
  • 179 + 8685379 = 8685558
  • 181 + 8685377 = 8685558
  • 191 + 8685367 = 8685558
  • 239 + 8685319 = 8685558

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 8,685,558 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 8685558 first appears in π at position 2,356 of the decimal expansion (the 2,356ordinal-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.
