Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185646, here are decompositions:

  • 5 + 185641 = 185646
  • 47 + 185599 = 185646
  • 53 + 185593 = 185646
  • 79 + 185567 = 185646
  • 89 + 185557 = 185646
  • 103 + 185543 = 185646
  • 107 + 185539 = 185646
  • 113 + 185533 = 185646

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 185,646 and was likely granted around 1875.

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

Position in π

The digit sequence 185646 first appears in π at position 715,799 of the decimal expansion (the 715,799ordinal-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.
