Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518182, here are decompositions:

  • 3 + 518179 = 518182
  • 11 + 518171 = 518182
  • 23 + 518159 = 518182
  • 29 + 518153 = 518182
  • 53 + 518129 = 518182
  • 59 + 518123 = 518182
  • 83 + 518099 = 518182
  • 191 + 517991 = 518182

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 518,182 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 518182 first appears in π at position 223,540 of the decimal expansion (the 223,540ordinal-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.
