Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185412, here are decompositions:

  • 11 + 185401 = 185412
  • 41 + 185371 = 185412
  • 43 + 185369 = 185412
  • 53 + 185359 = 185412
  • 89 + 185323 = 185412
  • 103 + 185309 = 185412
  • 109 + 185303 = 185412
  • 113 + 185299 = 185412

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 185,412 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 185412 first appears in π at position 819,530 of the decimal expansion (the 819,530ordinal-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.
