Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551244, here are decompositions:

  • 11 + 551233 = 551244
  • 13 + 551231 = 551244
  • 37 + 551207 = 551244
  • 47 + 551197 = 551244
  • 101 + 551143 = 551244
  • 131 + 551113 = 551244
  • 137 + 551107 = 551244
  • 151 + 551093 = 551244

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 551,244 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 551244 first appears in π at position 90,398 of the decimal expansion (the 90,398ordinal-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.
