Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492840, here are decompositions:

  • 41 + 492799 = 492840
  • 59 + 492781 = 492840
  • 71 + 492769 = 492840
  • 79 + 492761 = 492840
  • 83 + 492757 = 492840
  • 109 + 492731 = 492840
  • 167 + 492673 = 492840
  • 181 + 492659 = 492840

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 492,840 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 492840 first appears in π at position 304,121 of the decimal expansion (the 304,121ordinal-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.
