Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514132, here are decompositions:

19 + 31514113 = 31514132
31 + 31514101 = 31514132
73 + 31514059 = 31514132
109 + 31514023 = 31514132
241 + 31513891 = 31514132
283 + 31513849 = 31514132
313 + 31513819 = 31514132
439 + 31513693 = 31514132

Showing the first eight; more decompositions exist.
