Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19708, here are decompositions:

  • 11 + 19697 = 19708
  • 47 + 19661 = 19708
  • 131 + 19577 = 19708
  • 137 + 19571 = 19708
  • 149 + 19559 = 19708
  • 167 + 19541 = 19708
  • 239 + 19469 = 19708
  • 251 + 19457 = 19708

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19708 first appears in π at position 30,993 of the decimal expansion (the 30,993ordinal-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.
