Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23418, here are decompositions:

  • 19 + 23399 = 23418
  • 47 + 23371 = 23418
  • 61 + 23357 = 23418
  • 79 + 23339 = 23418
  • 97 + 23321 = 23418
  • 107 + 23311 = 23418
  • 127 + 23291 = 23418
  • 139 + 23279 = 23418

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23418 first appears in π at position 77,669 of the decimal expansion (the 77,669ordinal-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.
