Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25790, here are decompositions:

  • 19 + 25771 = 25790
  • 31 + 25759 = 25790
  • 43 + 25747 = 25790
  • 73 + 25717 = 25790
  • 97 + 25693 = 25790
  • 151 + 25639 = 25790
  • 157 + 25633 = 25790
  • 181 + 25609 = 25790

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25790 first appears in π at position 204,992 of the decimal expansion (the 204,992ordinal-suffix:nd 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.
