Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25426, here are decompositions:

  • 3 + 25423 = 25426
  • 17 + 25409 = 25426
  • 53 + 25373 = 25426
  • 59 + 25367 = 25426
  • 83 + 25343 = 25426
  • 173 + 25253 = 25426
  • 179 + 25247 = 25426
  • 197 + 25229 = 25426

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25426 first appears in π at position 260,841 of the decimal expansion (the 260,841ordinal-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.
