Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6806, here are decompositions:

  • 3 + 6803 = 6806
  • 13 + 6793 = 6806
  • 43 + 6763 = 6806
  • 73 + 6733 = 6806
  • 97 + 6709 = 6806
  • 103 + 6703 = 6806
  • 127 + 6679 = 6806
  • 199 + 6607 = 6806

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6806 first appears in π at position 966 of the decimal expansion (the 966ordinal-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.
