Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23510, here are decompositions:

  • 13 + 23497 = 23510
  • 37 + 23473 = 23510
  • 79 + 23431 = 23510
  • 139 + 23371 = 23510
  • 199 + 23311 = 23510
  • 241 + 23269 = 23510
  • 283 + 23227 = 23510
  • 307 + 23203 = 23510

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23510 first appears in π at position 113,949 of the decimal expansion (the 113,949ordinal-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.
