Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 936638, here are decompositions:

  • 19 + 936619 = 936638
  • 61 + 936577 = 936638
  • 127 + 936511 = 936638
  • 139 + 936499 = 936638
  • 151 + 936487 = 936638
  • 277 + 936361 = 936638
  • 379 + 936259 = 936638
  • 457 + 936181 = 936638

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 936,638 and was likely granted around 1909.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 936638 first appears in π at position 786,808 of the decimal expansion (the 786,808ordinal-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.
