Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521794, here are decompositions:

  • 3 + 521791 = 521794
  • 5 + 521789 = 521794
  • 17 + 521777 = 521794
  • 41 + 521753 = 521794
  • 71 + 521723 = 521794
  • 101 + 521693 = 521794
  • 137 + 521657 = 521794
  • 191 + 521603 = 521794

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 521,794 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 521794 first appears in π at position 769,234 of the decimal expansion (the 769,234ordinal-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.
