Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23240, here are decompositions:

  • 13 + 23227 = 23240
  • 31 + 23209 = 23240
  • 37 + 23203 = 23240
  • 43 + 23197 = 23240
  • 67 + 23173 = 23240
  • 73 + 23167 = 23240
  • 97 + 23143 = 23240
  • 109 + 23131 = 23240

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23240 first appears in π at position 13,329 of the decimal expansion (the 13,329ordinal-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.
