Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470440, here are decompositions:

  • 11 + 470429 = 470440
  • 23 + 470417 = 470440
  • 29 + 470411 = 470440
  • 41 + 470399 = 470440
  • 107 + 470333 = 470440
  • 137 + 470303 = 470440
  • 197 + 470243 = 470440
  • 227 + 470213 = 470440

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 470,440 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 470440 first appears in π at position 245,471 of the decimal expansion (the 245,471ordinal-suffix:st 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.
