Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690188, here are decompositions:

  • 11 + 8690177 = 8690188
  • 71 + 8690117 = 8690188
  • 191 + 8689997 = 8690188
  • 239 + 8689949 = 8690188
  • 347 + 8689841 = 8690188
  • 389 + 8689799 = 8690188
  • 461 + 8689727 = 8690188
  • 659 + 8689529 = 8690188

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 8,690,188 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 8690188 first appears in π at position 886,545 of the decimal expansion (the 886,545ordinal-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.
