Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23088, here are decompositions:

  • 7 + 23081 = 23088
  • 17 + 23071 = 23088
  • 29 + 23059 = 23088
  • 31 + 23057 = 23088
  • 47 + 23041 = 23088
  • 59 + 23029 = 23088
  • 61 + 23027 = 23088
  • 67 + 23021 = 23088

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23088 first appears in π at position 171,269 of the decimal expansion (the 171,269ordinal-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.
