Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39898, here are decompositions:

  • 11 + 39887 = 39898
  • 29 + 39869 = 39898
  • 41 + 39857 = 39898
  • 59 + 39839 = 39898
  • 71 + 39827 = 39898
  • 107 + 39791 = 39898
  • 137 + 39761 = 39898
  • 149 + 39749 = 39898

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39898 first appears in π at position 6,577 of the decimal expansion (the 6,577ordinal-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.
