Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3964, here are decompositions:

  • 17 + 3947 = 3964
  • 41 + 3923 = 3964
  • 47 + 3917 = 3964
  • 53 + 3911 = 3964
  • 83 + 3881 = 3964
  • 101 + 3863 = 3964
  • 113 + 3851 = 3964
  • 131 + 3833 = 3964

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3964 first appears in π at position 15,880 of the decimal expansion (the 15,880ordinal-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.
