Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518884, here are decompositions:

  • 17 + 518867 = 518884
  • 53 + 518831 = 518884
  • 71 + 518813 = 518884
  • 83 + 518801 = 518884
  • 137 + 518747 = 518884
  • 167 + 518717 = 518884
  • 227 + 518657 = 518884
  • 263 + 518621 = 518884

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 518,884 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 518884 first appears in π at position 437,904 of the decimal expansion (the 437,904ordinal-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.
