Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25136, here are decompositions:

  • 19 + 25117 = 25136
  • 79 + 25057 = 25136
  • 103 + 25033 = 25136
  • 157 + 24979 = 25136
  • 193 + 24943 = 25136
  • 229 + 24907 = 25136
  • 277 + 24859 = 25136
  • 337 + 24799 = 25136

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25136 first appears in π at position 27,147 of the decimal expansion (the 27,147ordinal-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.
