Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3950, here are decompositions:

  • 3 + 3947 = 3950
  • 7 + 3943 = 3950
  • 19 + 3931 = 3950
  • 31 + 3919 = 3950
  • 43 + 3907 = 3950
  • 61 + 3889 = 3950
  • 73 + 3877 = 3950
  • 97 + 3853 = 3950

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3950 first appears in π at position 6,663 of the decimal expansion (the 6,663ordinal-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.
