Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497920, here are decompositions:

  • 47 + 497873 = 497920
  • 53 + 497867 = 497920
  • 89 + 497831 = 497920
  • 107 + 497813 = 497920
  • 149 + 497771 = 497920
  • 179 + 497741 = 497920
  • 191 + 497729 = 497920
  • 257 + 497663 = 497920

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 497,920 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 497920 first appears in π at position 522,219 of the decimal expansion (the 522,219ordinal-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.
