Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76840, here are decompositions:

  • 3 + 76837 = 76840
  • 11 + 76829 = 76840
  • 59 + 76781 = 76840
  • 83 + 76757 = 76840
  • 107 + 76733 = 76840
  • 167 + 76673 = 76840
  • 173 + 76667 = 76840
  • 191 + 76649 = 76840

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 76840 first appears in π at position 62,993 of the decimal expansion (the 62,993ordinal-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.
