Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470780, here are decompositions:

  • 31 + 470749 = 470780
  • 61 + 470719 = 470780
  • 127 + 470653 = 470780
  • 181 + 470599 = 470780
  • 229 + 470551 = 470780
  • 241 + 470539 = 470780
  • 307 + 470473 = 470780
  • 337 + 470443 = 470780

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 470,780 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 470780 first appears in π at position 278,517 of the decimal expansion (the 278,517ordinal-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.
