Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25758, here are decompositions:

  • 11 + 25747 = 25758
  • 17 + 25741 = 25758
  • 41 + 25717 = 25758
  • 79 + 25679 = 25758
  • 101 + 25657 = 25758
  • 137 + 25621 = 25758
  • 149 + 25609 = 25758
  • 157 + 25601 = 25758

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25758 first appears in π at position 65,691 of the decimal expansion (the 65,691ordinal-suffix:st 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.
