Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39718, here are decompositions:

  • 47 + 39671 = 39718
  • 59 + 39659 = 39718
  • 137 + 39581 = 39718
  • 149 + 39569 = 39718
  • 167 + 39551 = 39718
  • 197 + 39521 = 39718
  • 257 + 39461 = 39718
  • 347 + 39371 = 39718

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39718 first appears in π at position 12,253 of the decimal expansion (the 12,253ordinal-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.
