Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470490, here are decompositions:

  • 17 + 470473 = 470490
  • 19 + 470471 = 470490
  • 29 + 470461 = 470490
  • 37 + 470453 = 470490
  • 43 + 470447 = 470490
  • 47 + 470443 = 470490
  • 61 + 470429 = 470490
  • 73 + 470417 = 470490

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 470,490 and was likely granted around 1891.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 470490 first appears in π at position 491,610 of the decimal expansion (the 491,610ordinal-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.
