Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512536, here are decompositions:

  • 5 + 512531 = 512536
  • 29 + 512507 = 512536
  • 107 + 512429 = 512536
  • 389 + 512147 = 512536
  • 443 + 512093 = 512536
  • 677 + 511859 = 512536
  • 743 + 511793 = 512536
  • 953 + 511583 = 512536

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 512,536 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 512536 first appears in π at position 945,751 of the decimal expansion (the 945,751ordinal-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.
