Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518486, here are decompositions:

  • 13 + 518473 = 518486
  • 19 + 518467 = 518486
  • 97 + 518389 = 518486
  • 277 + 518209 = 518486
  • 307 + 518179 = 518486
  • 349 + 518137 = 518486
  • 373 + 518113 = 518486
  • 439 + 518047 = 518486

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 518,486 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 518486 first appears in π at position 418,734 of the decimal expansion (the 418,734ordinal-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.
