Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551140, here are decompositions:

  • 11 + 551129 = 551140
  • 41 + 551099 = 551140
  • 47 + 551093 = 551140
  • 71 + 551069 = 551140
  • 101 + 551039 = 551140
  • 113 + 551027 = 551140
  • 137 + 551003 = 551140
  • 167 + 550973 = 551140

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 551,140 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 551140 first appears in π at position 258,703 of the decimal expansion (the 258,703ordinal-suffix:rd 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.
