Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19736, here are decompositions:

  • 19 + 19717 = 19736
  • 37 + 19699 = 19736
  • 127 + 19609 = 19736
  • 139 + 19597 = 19736
  • 193 + 19543 = 19736
  • 229 + 19507 = 19736
  • 307 + 19429 = 19736
  • 313 + 19423 = 19736

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19736 first appears in π at position 202,797 of the decimal expansion (the 202,797ordinal-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.
