Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550720, here are decompositions:

  • 3 + 550717 = 550720
  • 17 + 550703 = 550720
  • 29 + 550691 = 550720
  • 41 + 550679 = 550720
  • 59 + 550661 = 550720
  • 83 + 550637 = 550720
  • 89 + 550631 = 550720
  • 113 + 550607 = 550720

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 550,720 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 550720 first appears in π at position 294,422 of the decimal expansion (the 294,422ordinal-suffix:nd 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.
