Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185814, here are decompositions:

  • 17 + 185797 = 185814
  • 47 + 185767 = 185814
  • 61 + 185753 = 185814
  • 67 + 185747 = 185814
  • 103 + 185711 = 185814
  • 107 + 185707 = 185814
  • 131 + 185683 = 185814
  • 137 + 185677 = 185814

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 185,814 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 185814 first appears in π at position 576,484 of the decimal expansion (the 576,484ordinal-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.
