Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23560, here are decompositions:

  • 3 + 23557 = 23560
  • 11 + 23549 = 23560
  • 23 + 23537 = 23560
  • 29 + 23531 = 23560
  • 101 + 23459 = 23560
  • 113 + 23447 = 23560
  • 191 + 23369 = 23560
  • 227 + 23333 = 23560

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23560 first appears in π at position 260,684 of the decimal expansion (the 260,684ordinal-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.
