Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515632, here are decompositions:

  • 11 + 515621 = 515632
  • 53 + 515579 = 515632
  • 113 + 515519 = 515632
  • 251 + 515381 = 515632
  • 263 + 515369 = 515632
  • 281 + 515351 = 515632
  • 353 + 515279 = 515632
  • 401 + 515231 = 515632

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 515,632 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 515632 first appears in π at position 71,243 of the decimal expansion (the 71,243ordinal-suffix:rd 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.
