Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23516, here are decompositions:

  • 7 + 23509 = 23516
  • 19 + 23497 = 23516
  • 43 + 23473 = 23516
  • 223 + 23293 = 23516
  • 307 + 23209 = 23516
  • 313 + 23203 = 23516
  • 349 + 23167 = 23516
  • 373 + 23143 = 23516

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23516 first appears in π at position 17,090 of the decimal expansion (the 17,090ordinal-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.
