Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550638, here are decompositions:

  • 7 + 550631 = 550638
  • 17 + 550621 = 550638
  • 29 + 550609 = 550638
  • 31 + 550607 = 550638
  • 61 + 550577 = 550638
  • 97 + 550541 = 550638
  • 107 + 550531 = 550638
  • 149 + 550489 = 550638

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 550,638 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 550638 first appears in π at position 138,832 of the decimal expansion (the 138,832ordinal-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.
