Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3894, here are decompositions:

  • 5 + 3889 = 3894
  • 13 + 3881 = 3894
  • 17 + 3877 = 3894
  • 31 + 3863 = 3894
  • 41 + 3853 = 3894
  • 43 + 3851 = 3894
  • 47 + 3847 = 3894
  • 61 + 3833 = 3894

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3894 first appears in π at position 7,653 of the decimal expansion (the 7,653ordinal-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.
