Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551222, here are decompositions:

  • 3 + 551219 = 551222
  • 43 + 551179 = 551222
  • 79 + 551143 = 551222
  • 109 + 551113 = 551222
  • 163 + 551059 = 551222
  • 229 + 550993 = 551222
  • 271 + 550951 = 551222
  • 283 + 550939 = 551222

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 551,222 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 551222 first appears in π at position 659,244 of the decimal expansion (the 659,244ordinal-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.
