Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456064, here are decompositions:

43 + 31456021 = 31456064
61 + 31456003 = 31456064
103 + 31455961 = 31456064
163 + 31455901 = 31456064
223 + 31455841 = 31456064
313 + 31455751 = 31456064
337 + 31455727 = 31456064
433 + 31455631 = 31456064

Showing the first eight; more decompositions exist.
