Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25002, here are decompositions:

  • 13 + 24989 = 25002
  • 23 + 24979 = 25002
  • 31 + 24971 = 25002
  • 59 + 24943 = 25002
  • 79 + 24923 = 25002
  • 83 + 24919 = 25002
  • 113 + 24889 = 25002
  • 151 + 24851 = 25002

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25002 first appears in π at position 13,374 of the decimal expansion (the 13,374ordinal-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.
