Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185942, here are decompositions:

  • 19 + 185923 = 185942
  • 73 + 185869 = 185942
  • 109 + 185833 = 185942
  • 193 + 185749 = 185942
  • 349 + 185593 = 185942
  • 373 + 185569 = 185942
  • 409 + 185533 = 185942
  • 541 + 185401 = 185942

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 185,942 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 185942 first appears in π at position 846,321 of the decimal expansion (the 846,321ordinal-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.
