Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479064, here are decompositions:

3 + 31479061 = 31479064
47 + 31479017 = 31479064
107 + 31478957 = 31479064
131 + 31478933 = 31479064
233 + 31478831 = 31479064
257 + 31478807 = 31479064
593 + 31478471 = 31479064
653 + 31478411 = 31479064

Showing the first eight; more decompositions exist.
