Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25458, here are decompositions:

  • 5 + 25453 = 25458
  • 11 + 25447 = 25458
  • 19 + 25439 = 25458
  • 47 + 25411 = 25458
  • 67 + 25391 = 25458
  • 101 + 25357 = 25458
  • 109 + 25349 = 25458
  • 137 + 25321 = 25458

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25458 first appears in π at position 114,428 of the decimal expansion (the 114,428ordinal-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.
