Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23810, here are decompositions:

  • 37 + 23773 = 23810
  • 43 + 23767 = 23810
  • 67 + 23743 = 23810
  • 139 + 23671 = 23810
  • 181 + 23629 = 23810
  • 211 + 23599 = 23810
  • 229 + 23581 = 23810
  • 271 + 23539 = 23810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23810 first appears in π at position 18,903 of the decimal expansion (the 18,903ordinal-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.
