Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514328, here are decompositions:

19 + 31514309 = 31514328
31 + 31514297 = 31514328
37 + 31514291 = 31514328
61 + 31514267 = 31514328
67 + 31514261 = 31514328
89 + 31514239 = 31514328
107 + 31514221 = 31514328
137 + 31514191 = 31514328

Showing the first eight; more decompositions exist.
