Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12698, here are decompositions:

  • 61 + 12637 = 12698
  • 79 + 12619 = 12698
  • 97 + 12601 = 12698
  • 109 + 12589 = 12698
  • 151 + 12547 = 12698
  • 157 + 12541 = 12698
  • 181 + 12517 = 12698
  • 211 + 12487 = 12698

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12698 first appears in π at position 214,773 of the decimal expansion (the 214,773ordinal-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.
