Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185358, here are decompositions:

  • 31 + 185327 = 185358
  • 59 + 185299 = 185358
  • 67 + 185291 = 185358
  • 137 + 185221 = 185358
  • 181 + 185177 = 185358
  • 191 + 185167 = 185358
  • 197 + 185161 = 185358
  • 227 + 185131 = 185358

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 185,358 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 185358 first appears in π at position 3,596 of the decimal expansion (the 3,596ordinal-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.
