Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25242, here are decompositions:

  • 5 + 25237 = 25242
  • 13 + 25229 = 25242
  • 23 + 25219 = 25242
  • 53 + 25189 = 25242
  • 59 + 25183 = 25242
  • 71 + 25171 = 25242
  • 73 + 25169 = 25242
  • 79 + 25163 = 25242

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25242 first appears in π at position 218,545 of the decimal expansion (the 218,545ordinal-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.
