Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25456, here are decompositions:

  • 3 + 25453 = 25456
  • 17 + 25439 = 25456
  • 47 + 25409 = 25456
  • 83 + 25373 = 25456
  • 89 + 25367 = 25456
  • 107 + 25349 = 25456
  • 113 + 25343 = 25456
  • 149 + 25307 = 25456

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25456 first appears in π at position 8,034 of the decimal expansion (the 8,034ordinal-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.
