Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528134, here are decompositions:

7 + 31528127 = 31528134
13 + 31528121 = 31528134
23 + 31528111 = 31528134
31 + 31528103 = 31528134
41 + 31528093 = 31528134
67 + 31528067 = 31528134
97 + 31528037 = 31528134
137 + 31527997 = 31528134

Showing the first eight; more decompositions exist.
