Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470818, here are decompositions:

  • 107 + 470711 = 470818
  • 149 + 470669 = 470818
  • 167 + 470651 = 470818
  • 191 + 470627 = 470818
  • 197 + 470621 = 470818
  • 239 + 470579 = 470818
  • 317 + 470501 = 470818
  • 347 + 470471 = 470818

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 470,818 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 470818 first appears in π at position 902,840 of the decimal expansion (the 902,840ordinal-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.
