Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9928, here are decompositions:

  • 5 + 9923 = 9928
  • 41 + 9887 = 9928
  • 71 + 9857 = 9928
  • 89 + 9839 = 9928
  • 137 + 9791 = 9928
  • 179 + 9749 = 9928
  • 239 + 9689 = 9928
  • 251 + 9677 = 9928

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9928 first appears in π at position 7,836 of the decimal expansion (the 7,836ordinal-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.
