Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521064, here are decompositions:

  • 13 + 521051 = 521064
  • 17 + 521047 = 521064
  • 23 + 521041 = 521064
  • 41 + 521023 = 521064
  • 43 + 521021 = 521064
  • 83 + 520981 = 521064
  • 97 + 520967 = 521064
  • 101 + 520963 = 521064

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 521,064 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 521064 first appears in π at position 974,581 of the decimal expansion (the 974,581ordinal-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.
