Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12746, here are decompositions:

  • 3 + 12743 = 12746
  • 7 + 12739 = 12746
  • 43 + 12703 = 12746
  • 109 + 12637 = 12746
  • 127 + 12619 = 12746
  • 157 + 12589 = 12746
  • 163 + 12583 = 12746
  • 193 + 12553 = 12746

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12746 first appears in π at position 14,448 of the decimal expansion (the 14,448ordinal-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.
