Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185770, here are decompositions:

  • 3 + 185767 = 185770
  • 17 + 185753 = 185770
  • 23 + 185747 = 185770
  • 47 + 185723 = 185770
  • 59 + 185711 = 185770
  • 71 + 185699 = 185770
  • 89 + 185681 = 185770
  • 149 + 185621 = 185770

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 185,770 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 185770 first appears in π at position 463,813 of the decimal expansion (the 463,813ordinal-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.
