Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518090, here are decompositions:

  • 7 + 518083 = 518090
  • 31 + 518059 = 518090
  • 43 + 518047 = 518090
  • 73 + 518017 = 518090
  • 109 + 517981 = 518090
  • 163 + 517927 = 518090
  • 229 + 517861 = 518090
  • 373 + 517717 = 518090

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 518,090 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 518090 first appears in π at position 102,459 of the decimal expansion (the 102,459ordinal-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.
