Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513256, here are decompositions:

  • 17 + 513239 = 513256
  • 53 + 513203 = 513256
  • 83 + 513173 = 513256
  • 89 + 513167 = 513256
  • 173 + 513083 = 513256
  • 197 + 513059 = 513256
  • 239 + 513017 = 513256
  • 257 + 512999 = 513256

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 513,256 and was likely granted around 1893.

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

Position in π

The digit sequence 513256 first appears in π at position 35,500 of the decimal expansion (the 35,500ordinal-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.
