Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19698, here are decompositions:

  • 11 + 19687 = 19698
  • 17 + 19681 = 19698
  • 37 + 19661 = 19698
  • 89 + 19609 = 19698
  • 101 + 19597 = 19698
  • 127 + 19571 = 19698
  • 139 + 19559 = 19698
  • 157 + 19541 = 19698

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19698 first appears in π at position 38,393 of the decimal expansion (the 38,393ordinal-suffix:rd 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.
