Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521702, here are decompositions:

  • 31 + 521671 = 521702
  • 43 + 521659 = 521702
  • 61 + 521641 = 521702
  • 151 + 521551 = 521702
  • 163 + 521539 = 521702
  • 199 + 521503 = 521702
  • 211 + 521491 = 521702
  • 373 + 521329 = 521702

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 521,702 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 521702 first appears in π at position 740,795 of the decimal expansion (the 740,795ordinal-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.
