Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39860, here are decompositions:

  • 3 + 39857 = 39860
  • 13 + 39847 = 39860
  • 19 + 39841 = 39860
  • 31 + 39829 = 39860
  • 61 + 39799 = 39860
  • 127 + 39733 = 39860
  • 151 + 39709 = 39860
  • 157 + 39703 = 39860

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39860 first appears in π at position 14,925 of the decimal expansion (the 14,925ordinal-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.
