Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61908, here are decompositions:

  • 29 + 61879 = 61908
  • 37 + 61871 = 61908
  • 47 + 61861 = 61908
  • 71 + 61837 = 61908
  • 89 + 61819 = 61908
  • 127 + 61781 = 61908
  • 151 + 61757 = 61908
  • 157 + 61751 = 61908

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61908 first appears in π at position 49,792 of the decimal expansion (the 49,792ordinal-suffix:nd 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.
