Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521338, here are decompositions:

  • 29 + 521309 = 521338
  • 71 + 521267 = 521338
  • 107 + 521231 = 521338
  • 137 + 521201 = 521338
  • 317 + 521021 = 521338
  • 449 + 520889 = 521338
  • 617 + 520721 = 521338
  • 647 + 520691 = 521338

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 521,338 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 521338 first appears in π at position 213,792 of the decimal expansion (the 213,792ordinal-suffix:nd 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.
