Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551144, here are decompositions:

  • 31 + 551113 = 551144
  • 37 + 551107 = 551144
  • 127 + 551017 = 551144
  • 151 + 550993 = 551144
  • 193 + 550951 = 551144
  • 241 + 550903 = 551144
  • 283 + 550861 = 551144
  • 313 + 550831 = 551144

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 551,144 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 551144 first appears in π at position 75,730 of the decimal expansion (the 75,730ordinal-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.
