Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39894, here are decompositions:

  • 7 + 39887 = 39894
  • 11 + 39883 = 39894
  • 17 + 39877 = 39894
  • 31 + 39863 = 39894
  • 37 + 39857 = 39894
  • 47 + 39847 = 39894
  • 53 + 39841 = 39894
  • 67 + 39827 = 39894

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39894 first appears in π at position 44,343 of the decimal expansion (the 44,343ordinal-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.
