Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12826, here are decompositions:

  • 3 + 12823 = 12826
  • 5 + 12821 = 12826
  • 17 + 12809 = 12826
  • 83 + 12743 = 12826
  • 113 + 12713 = 12826
  • 137 + 12689 = 12826
  • 167 + 12659 = 12826
  • 173 + 12653 = 12826

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12826 first appears in π at position 52,224 of the decimal expansion (the 52,224ordinal-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.
