Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23188, here are decompositions:

  • 29 + 23159 = 23188
  • 71 + 23117 = 23188
  • 89 + 23099 = 23188
  • 101 + 23087 = 23188
  • 107 + 23081 = 23188
  • 131 + 23057 = 23188
  • 149 + 23039 = 23188
  • 167 + 23021 = 23188

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23188 first appears in π at position 304,339 of the decimal expansion (the 304,339ordinal-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.
