Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6778, here are decompositions:

  • 17 + 6761 = 6778
  • 41 + 6737 = 6778
  • 59 + 6719 = 6778
  • 89 + 6689 = 6778
  • 179 + 6599 = 6778
  • 197 + 6581 = 6778
  • 227 + 6551 = 6778
  • 257 + 6521 = 6778

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6778 first appears in π at position 6,173 of the decimal expansion (the 6,173ordinal-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.
