Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559214, here are decompositions:

7 + 31559207 = 31559214
53 + 31559161 = 31559214
83 + 31559131 = 31559214
163 + 31559051 = 31559214
241 + 31558973 = 31559214
251 + 31558963 = 31559214
257 + 31558957 = 31559214
317 + 31558897 = 31559214

Showing the first eight; more decompositions exist.
