Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25320, here are decompositions:

  • 11 + 25309 = 25320
  • 13 + 25307 = 25320
  • 17 + 25303 = 25320
  • 19 + 25301 = 25320
  • 59 + 25261 = 25320
  • 67 + 25253 = 25320
  • 73 + 25247 = 25320
  • 83 + 25237 = 25320

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25320 first appears in π at position 78,479 of the decimal expansion (the 78,479ordinal-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.
