Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3958, here are decompositions:

  • 11 + 3947 = 3958
  • 29 + 3929 = 3958
  • 41 + 3917 = 3958
  • 47 + 3911 = 3958
  • 107 + 3851 = 3958
  • 137 + 3821 = 3958
  • 179 + 3779 = 3958
  • 191 + 3767 = 3958

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3958 first appears in π at position 18,721 of the decimal expansion (the 18,721ordinal-suffix:st 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.
