Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550640, here are decompositions:

  • 3 + 550637 = 550640
  • 19 + 550621 = 550640
  • 31 + 550609 = 550640
  • 109 + 550531 = 550640
  • 127 + 550513 = 550640
  • 151 + 550489 = 550640
  • 193 + 550447 = 550640
  • 199 + 550441 = 550640

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 550,640 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 550640 first appears in π at position 181,821 of the decimal expansion (the 181,821ordinal-suffix:st 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.
