Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23858, here are decompositions:

  • 31 + 23827 = 23858
  • 97 + 23761 = 23858
  • 139 + 23719 = 23858
  • 181 + 23677 = 23858
  • 229 + 23629 = 23858
  • 277 + 23581 = 23858
  • 349 + 23509 = 23858
  • 487 + 23371 = 23858

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23858 first appears in π at position 519,948 of the decimal expansion (the 519,948ordinal-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.
