Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25008, here are decompositions:

  • 19 + 24989 = 25008
  • 29 + 24979 = 25008
  • 31 + 24977 = 25008
  • 37 + 24971 = 25008
  • 41 + 24967 = 25008
  • 89 + 24919 = 25008
  • 101 + 24907 = 25008
  • 131 + 24877 = 25008

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25008 first appears in π at position 82,335 of the decimal expansion (the 82,335ordinal-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.
