Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518088, here are decompositions:

  • 5 + 518083 = 518088
  • 29 + 518059 = 518088
  • 31 + 518057 = 518088
  • 41 + 518047 = 518088
  • 71 + 518017 = 518088
  • 89 + 517999 = 518088
  • 97 + 517991 = 518088
  • 107 + 517981 = 518088

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 518,088 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 518088 first appears in π at position 636,537 of the decimal expansion (the 636,537ordinal-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.
