Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551746, here are decompositions:

  • 3 + 551743 = 551746
  • 17 + 551729 = 551746
  • 23 + 551723 = 551746
  • 29 + 551717 = 551746
  • 53 + 551693 = 551746
  • 149 + 551597 = 551746
  • 197 + 551549 = 551746
  • 227 + 551519 = 551746

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 551,746 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 551746 first appears in π at position 671,793 of the decimal expansion (the 671,793ordinal-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.
