Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25826, here are decompositions:

  • 7 + 25819 = 25826
  • 67 + 25759 = 25826
  • 79 + 25747 = 25826
  • 109 + 25717 = 25826
  • 193 + 25633 = 25826
  • 223 + 25603 = 25826
  • 373 + 25453 = 25826
  • 379 + 25447 = 25826

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25826 first appears in π at position 457,107 of the decimal expansion (the 457,107ordinal-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.
