Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555986, here are decompositions:

  • 19 + 555967 = 555986
  • 157 + 555829 = 555986
  • 163 + 555823 = 555986
  • 349 + 555637 = 555986
  • 397 + 555589 = 555986
  • 463 + 555523 = 555986
  • 499 + 555487 = 555986
  • 547 + 555439 = 555986

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 555,986 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 555986 first appears in π at position 106,862 of the decimal expansion (the 106,862ordinal-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.
