Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15226, here are decompositions:

  • 53 + 15173 = 15226
  • 89 + 15137 = 15226
  • 149 + 15077 = 15226
  • 173 + 15053 = 15226
  • 257 + 14969 = 15226
  • 269 + 14957 = 15226
  • 347 + 14879 = 15226
  • 359 + 14867 = 15226

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15226 first appears in π at position 27,706 of the decimal expansion (the 27,706ordinal-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.
