Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12288, here are decompositions:

  • 7 + 12281 = 12288
  • 11 + 12277 = 12288
  • 19 + 12269 = 12288
  • 37 + 12251 = 12288
  • 47 + 12241 = 12288
  • 61 + 12227 = 12288
  • 127 + 12161 = 12288
  • 131 + 12157 = 12288

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12288 first appears in π at position 238,240 of the decimal expansion (the 238,240ordinal-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.
