Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9778, here are decompositions:

  • 11 + 9767 = 9778
  • 29 + 9749 = 9778
  • 59 + 9719 = 9778
  • 89 + 9689 = 9778
  • 101 + 9677 = 9778
  • 149 + 9629 = 9778
  • 191 + 9587 = 9778
  • 227 + 9551 = 9778

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9778 first appears in π at position 6,783 of the decimal expansion (the 6,783ordinal-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.
