Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505168, here are decompositions:

  • 11 + 505157 = 505168
  • 29 + 505139 = 505168
  • 71 + 505097 = 505168
  • 101 + 505067 = 505168
  • 107 + 505061 = 505168
  • 137 + 505031 = 505168
  • 179 + 504989 = 505168
  • 239 + 504929 = 505168

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 505,168 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 505168 first appears in π at position 431,690 of the decimal expansion (the 431,690ordinal-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.
