Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518836, here are decompositions:

  • 5 + 518831 = 518836
  • 23 + 518813 = 518836
  • 29 + 518807 = 518836
  • 89 + 518747 = 518836
  • 107 + 518729 = 518836
  • 137 + 518699 = 518836
  • 179 + 518657 = 518836
  • 239 + 518597 = 518836

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 518,836 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 518836 first appears in π at position 538,893 of the decimal expansion (the 538,893ordinal-suffix:rd 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.
