Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9786, here are decompositions:

  • 5 + 9781 = 9786
  • 17 + 9769 = 9786
  • 19 + 9767 = 9786
  • 37 + 9749 = 9786
  • 43 + 9743 = 9786
  • 47 + 9739 = 9786
  • 53 + 9733 = 9786
  • 67 + 9719 = 9786

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9786 first appears in π at position 17,173 of the decimal expansion (the 17,173ordinal-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.
