Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598268, here are decompositions:

7 + 31598261 = 31598268
29 + 31598239 = 31598268
41 + 31598227 = 31598268
67 + 31598201 = 31598268
89 + 31598179 = 31598268
127 + 31598141 = 31598268
131 + 31598137 = 31598268
167 + 31598101 = 31598268

Showing the first eight; more decompositions exist.
