Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508990, here are decompositions:

  • 3 + 508987 = 508990
  • 17 + 508973 = 508990
  • 29 + 508961 = 508990
  • 47 + 508943 = 508990
  • 59 + 508931 = 508990
  • 71 + 508919 = 508990
  • 89 + 508901 = 508990
  • 149 + 508841 = 508990

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 508,990 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 508990 first appears in π at position 205,847 of the decimal expansion (the 205,847ordinal-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.
