Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18710, here are decompositions:

  • 19 + 18691 = 18710
  • 31 + 18679 = 18710
  • 73 + 18637 = 18710
  • 127 + 18583 = 18710
  • 157 + 18553 = 18710
  • 193 + 18517 = 18710
  • 229 + 18481 = 18710
  • 271 + 18439 = 18710

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18710 first appears in π at position 27,304 of the decimal expansion (the 27,304ordinal-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.
