Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518252, here are decompositions:

  • 3 + 518249 = 518252
  • 13 + 518239 = 518252
  • 19 + 518233 = 518252
  • 43 + 518209 = 518252
  • 61 + 518191 = 518252
  • 73 + 518179 = 518252
  • 139 + 518113 = 518252
  • 151 + 518101 = 518252

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 518,252 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 518252 first appears in π at position 67,229 of the decimal expansion (the 67,229ordinal-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.
