Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185030, here are decompositions:

  • 3 + 185027 = 185030
  • 31 + 184999 = 185030
  • 37 + 184993 = 185030
  • 61 + 184969 = 185030
  • 73 + 184957 = 185030
  • 127 + 184903 = 185030
  • 151 + 184879 = 185030
  • 193 + 184837 = 185030

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 185,030 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 185030 first appears in π at position 440,600 of the decimal expansion (the 440,600ordinal-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.
