Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13208, here are decompositions:

  • 31 + 13177 = 13208
  • 37 + 13171 = 13208
  • 61 + 13147 = 13208
  • 109 + 13099 = 13208
  • 199 + 13009 = 13208
  • 229 + 12979 = 13208
  • 241 + 12967 = 13208
  • 367 + 12841 = 13208

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13208 first appears in π at position 23,116 of the decimal expansion (the 23,116ordinal-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.
