Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91908, here are decompositions:

  • 41 + 91867 = 91908
  • 67 + 91841 = 91908
  • 71 + 91837 = 91908
  • 97 + 91811 = 91908
  • 101 + 91807 = 91908
  • 107 + 91801 = 91908
  • 127 + 91781 = 91908
  • 137 + 91771 = 91908

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 91908 first appears in π at position 163,333 of the decimal expansion (the 163,333ordinal-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.
