Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25586, here are decompositions:

  • 3 + 25583 = 25586
  • 7 + 25579 = 25586
  • 139 + 25447 = 25586
  • 163 + 25423 = 25586
  • 229 + 25357 = 25586
  • 277 + 25309 = 25586
  • 283 + 25303 = 25586
  • 349 + 25237 = 25586

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25586 first appears in π at position 50,012 of the decimal expansion (the 50,012ordinal-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.
