Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505868, here are decompositions:

  • 109 + 505759 = 505868
  • 157 + 505711 = 505868
  • 199 + 505669 = 505868
  • 211 + 505657 = 505868
  • 229 + 505639 = 505868
  • 331 + 505537 = 505868
  • 367 + 505501 = 505868
  • 409 + 505459 = 505868

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 505,868 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 505868 first appears in π at position 60,406 of the decimal expansion (the 60,406ordinal-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.
