Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492820, here are decompositions:

  • 59 + 492761 = 492820
  • 89 + 492731 = 492820
  • 101 + 492719 = 492820
  • 113 + 492707 = 492820
  • 149 + 492671 = 492820
  • 173 + 492647 = 492820
  • 179 + 492641 = 492820
  • 191 + 492629 = 492820

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 492,820 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 492820 first appears in π at position 791,129 of the decimal expansion (the 791,129ordinal-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.
