Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499942, here are decompositions:

  • 59 + 499883 = 499942
  • 89 + 499853 = 499942
  • 251 + 499691 = 499942
  • 263 + 499679 = 499942
  • 269 + 499673 = 499942
  • 281 + 499661 = 499942
  • 293 + 499649 = 499942
  • 383 + 499559 = 499942

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 499,942 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 499942 first appears in π at position 152,707 of the decimal expansion (the 152,707ordinal-suffix:th 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.
