Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521704, here are decompositions:

  • 11 + 521693 = 521704
  • 47 + 521657 = 521704
  • 101 + 521603 = 521704
  • 137 + 521567 = 521704
  • 167 + 521537 = 521704
  • 233 + 521471 = 521704
  • 257 + 521447 = 521704
  • 311 + 521393 = 521704

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 521,704 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 521704 first appears in π at position 84,948 of the decimal expansion (the 84,948ordinal-suffix:th 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.
