Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494090, here are decompositions:

  • 7 + 494083 = 494090
  • 13 + 494077 = 494090
  • 61 + 494029 = 494090
  • 67 + 494023 = 494090
  • 97 + 493993 = 494090
  • 151 + 493939 = 494090
  • 193 + 493897 = 494090
  • 277 + 493813 = 494090

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 494,090 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 494090 first appears in π at position 600,718 of the decimal expansion (the 600,718ordinal-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.
