Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551268, here are decompositions:

  • 37 + 551231 = 551268
  • 61 + 551207 = 551268
  • 71 + 551197 = 551268
  • 89 + 551179 = 551268
  • 139 + 551129 = 551268
  • 199 + 551069 = 551268
  • 229 + 551039 = 551268
  • 241 + 551027 = 551268

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 551,268 and was likely granted around 1895.

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

Position in π

The digit sequence 551268 first appears in π at position 42,444 of the decimal expansion (the 42,444ordinal-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.
