Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25288, here are decompositions:

  • 41 + 25247 = 25288
  • 59 + 25229 = 25288
  • 167 + 25121 = 25288
  • 191 + 25097 = 25288
  • 251 + 25037 = 25288
  • 257 + 25031 = 25288
  • 311 + 24977 = 25288
  • 317 + 24971 = 25288

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25288 first appears in π at position 93,652 of the decimal expansion (the 93,652ordinal-suffix:nd 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.
