Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13066, here are decompositions:

  • 3 + 13063 = 13066
  • 17 + 13049 = 13066
  • 23 + 13043 = 13066
  • 29 + 13037 = 13066
  • 59 + 13007 = 13066
  • 83 + 12983 = 13066
  • 107 + 12959 = 13066
  • 113 + 12953 = 13066

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13066 first appears in π at position 434,223 of the decimal expansion (the 434,223ordinal-suffix:rd 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.
