Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499966, here are decompositions:

  • 23 + 499943 = 499966
  • 83 + 499883 = 499966
  • 113 + 499853 = 499966
  • 179 + 499787 = 499966
  • 227 + 499739 = 499966
  • 293 + 499673 = 499966
  • 317 + 499649 = 499966
  • 359 + 499607 = 499966

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 499,966 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 499966 first appears in π at position 631,851 of the decimal expansion (the 631,851ordinal-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.
