Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185868, here are decompositions:

  • 19 + 185849 = 185868
  • 37 + 185831 = 185868
  • 47 + 185821 = 185868
  • 71 + 185797 = 185868
  • 79 + 185789 = 185868
  • 101 + 185767 = 185868
  • 131 + 185737 = 185868
  • 157 + 185711 = 185868

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 185,868 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 185868 first appears in π at position 476,901 of the decimal expansion (the 476,901ordinal-suffix:st 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.
