Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186080, here are decompositions:

  • 31 + 186049 = 186080
  • 43 + 186037 = 186080
  • 61 + 186019 = 186080
  • 67 + 186013 = 186080
  • 73 + 186007 = 186080
  • 109 + 185971 = 186080
  • 157 + 185923 = 186080
  • 163 + 185917 = 186080

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 186,080 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 186080 first appears in π at position 642,705 of the decimal expansion (the 642,705ordinal-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.
