Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518634, here are decompositions:

  • 13 + 518621 = 518634
  • 23 + 518611 = 518634
  • 37 + 518597 = 518634
  • 47 + 518587 = 518634
  • 101 + 518533 = 518634
  • 113 + 518521 = 518634
  • 163 + 518471 = 518634
  • 167 + 518467 = 518634

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 518,634 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 518634 first appears in π at position 983,969 of the decimal expansion (the 983,969ordinal-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.
