Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534288, here are decompositions:

17 + 31534271 = 31534288
41 + 31534247 = 31534288
47 + 31534241 = 31534288
89 + 31534199 = 31534288
101 + 31534187 = 31534288
167 + 31534121 = 31534288
449 + 31533839 = 31534288
647 + 31533641 = 31534288

Showing the first eight; more decompositions exist.
