Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6722, here are decompositions:

  • 3 + 6719 = 6722
  • 13 + 6709 = 6722
  • 19 + 6703 = 6722
  • 31 + 6691 = 6722
  • 43 + 6679 = 6722
  • 61 + 6661 = 6722
  • 103 + 6619 = 6722
  • 151 + 6571 = 6722

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6722 first appears in π at position 2,549 of the decimal expansion (the 2,549ordinal-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.
