Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515468, here are decompositions:

  • 67 + 515401 = 515468
  • 97 + 515371 = 515468
  • 157 + 515311 = 515468
  • 241 + 515227 = 515468
  • 277 + 515191 = 515468
  • 379 + 515089 = 515468
  • 601 + 514867 = 515468
  • 727 + 514741 = 515468

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 515,468 and was likely granted around 1894.

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

Position in π

The digit sequence 515468 first appears in π at position 779,234 of the decimal expansion (the 779,234ordinal-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.
