Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25502, here are decompositions:

  • 31 + 25471 = 25502
  • 79 + 25423 = 25502
  • 163 + 25339 = 25502
  • 181 + 25321 = 25502
  • 193 + 25309 = 25502
  • 199 + 25303 = 25502
  • 241 + 25261 = 25502
  • 283 + 25219 = 25502

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25502 first appears in π at position 1,743 of the decimal expansion (the 1,743ordinal-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.
