Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6782, here are decompositions:

  • 3 + 6779 = 6782
  • 19 + 6763 = 6782
  • 73 + 6709 = 6782
  • 79 + 6703 = 6782
  • 103 + 6679 = 6782
  • 109 + 6673 = 6782
  • 163 + 6619 = 6782
  • 211 + 6571 = 6782

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6782 first appears in π at position 1,401 of the decimal expansion (the 1,401ordinal-suffix:st 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.
