Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25350, here are decompositions:

  • 7 + 25343 = 25350
  • 11 + 25339 = 25350
  • 29 + 25321 = 25350
  • 41 + 25309 = 25350
  • 43 + 25307 = 25350
  • 47 + 25303 = 25350
  • 89 + 25261 = 25350
  • 97 + 25253 = 25350

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25350 first appears in π at position 32,893 of the decimal expansion (the 32,893ordinal-suffix:rd 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.
