Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25582, here are decompositions:

  • 3 + 25579 = 25582
  • 5 + 25577 = 25582
  • 41 + 25541 = 25582
  • 59 + 25523 = 25582
  • 113 + 25469 = 25582
  • 173 + 25409 = 25582
  • 191 + 25391 = 25582
  • 233 + 25349 = 25582

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25582 first appears in π at position 423,131 of the decimal expansion (the 423,131ordinal-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.
