Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19604, here are decompositions:

  • 7 + 19597 = 19604
  • 61 + 19543 = 19604
  • 73 + 19531 = 19604
  • 97 + 19507 = 19604
  • 103 + 19501 = 19604
  • 127 + 19477 = 19604
  • 157 + 19447 = 19604
  • 163 + 19441 = 19604

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19604 first appears in π at position 83,738 of the decimal expansion (the 83,738ordinal-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.
