Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515576, here are decompositions:

  • 13 + 515563 = 515576
  • 37 + 515539 = 515576
  • 199 + 515377 = 515576
  • 283 + 515293 = 515576
  • 349 + 515227 = 515576
  • 433 + 515143 = 515576
  • 487 + 515089 = 515576
  • 643 + 514933 = 515576

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 515,576 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 515576 first appears in π at position 411,451 of the decimal expansion (the 411,451ordinal-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.
