Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512516, here are decompositions:

  • 13 + 512503 = 512516
  • 19 + 512497 = 512516
  • 73 + 512443 = 512516
  • 97 + 512419 = 512516
  • 127 + 512389 = 512516
  • 163 + 512353 = 512516
  • 229 + 512287 = 512516
  • 349 + 512167 = 512516

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 512,516 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 512516 first appears in π at position 974,235 of the decimal expansion (the 974,235ordinal-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.
