Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25078, here are decompositions:

  • 5 + 25073 = 25078
  • 41 + 25037 = 25078
  • 47 + 25031 = 25078
  • 89 + 24989 = 25078
  • 101 + 24977 = 25078
  • 107 + 24971 = 25078
  • 227 + 24851 = 25078
  • 257 + 24821 = 25078

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25078 first appears in π at position 468,240 of the decimal expansion (the 468,240ordinal-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.
