Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501528, here are decompositions:

  • 17 + 501511 = 501528
  • 101 + 501427 = 501528
  • 109 + 501419 = 501528
  • 127 + 501401 = 501528
  • 211 + 501317 = 501528
  • 229 + 501299 = 501528
  • 241 + 501287 = 501528
  • 257 + 501271 = 501528

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 501,528 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 501528 first appears in π at position 436,091 of the decimal expansion (the 436,091ordinal-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.
