Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186908, here are decompositions:

  • 19 + 186889 = 186908
  • 31 + 186877 = 186908
  • 37 + 186871 = 186908
  • 67 + 186841 = 186908
  • 109 + 186799 = 186908
  • 151 + 186757 = 186908
  • 181 + 186727 = 186908
  • 199 + 186709 = 186908

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 186,908 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 186908 first appears in π at position 797,822 of the decimal expansion (the 797,822ordinal-suffix:nd 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.
