Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181074, here are decompositions:

  • 11 + 181063 = 181074
  • 13 + 181061 = 181074
  • 43 + 181031 = 181074
  • 71 + 181003 = 181074
  • 73 + 181001 = 181074
  • 167 + 180907 = 181074
  • 191 + 180883 = 181074
  • 227 + 180847 = 181074

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 181,074 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 181074 first appears in π at position 305,389 of the decimal expansion (the 305,389ordinal-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.
