Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23512, here are decompositions:

  • 3 + 23509 = 23512
  • 53 + 23459 = 23512
  • 113 + 23399 = 23512
  • 173 + 23339 = 23512
  • 179 + 23333 = 23512
  • 191 + 23321 = 23512
  • 233 + 23279 = 23512
  • 311 + 23201 = 23512

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23512 first appears in π at position 60,724 of the decimal expansion (the 60,724ordinal-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.
