Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518802, here are decompositions:

  • 23 + 518779 = 518802
  • 41 + 518761 = 518802
  • 43 + 518759 = 518802
  • 59 + 518743 = 518802
  • 61 + 518741 = 518802
  • 73 + 518729 = 518802
  • 103 + 518699 = 518802
  • 113 + 518689 = 518802

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 518,802 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 518802 first appears in π at position 819,927 of the decimal expansion (the 819,927ordinal-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.
