Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 459840, here are decompositions:

  • 11 + 459829 = 459840
  • 23 + 459817 = 459840
  • 37 + 459803 = 459840
  • 137 + 459703 = 459840
  • 149 + 459691 = 459840
  • 163 + 459677 = 459840
  • 191 + 459649 = 459840
  • 193 + 459647 = 459840

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 459,840 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 459840 first appears in π at position 237,866 of the decimal expansion (the 237,866ordinal-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.
