Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186874, here are decompositions:

  • 3 + 186871 = 186874
  • 5 + 186869 = 186874
  • 101 + 186773 = 186874
  • 113 + 186761 = 186874
  • 131 + 186743 = 186874
  • 167 + 186707 = 186874
  • 173 + 186701 = 186874
  • 227 + 186647 = 186874

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 186,874 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 186874 first appears in π at position 760,716 of the decimal expansion (the 760,716ordinal-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.
