Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515590, here are decompositions:

  • 3 + 515587 = 515590
  • 11 + 515579 = 515590
  • 71 + 515519 = 515590
  • 83 + 515507 = 515590
  • 113 + 515477 = 515590
  • 233 + 515357 = 515590
  • 239 + 515351 = 515590
  • 311 + 515279 = 515590

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 515,590 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 515590 first appears in π at position 31,206 of the decimal expansion (the 31,206ordinal-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.
