Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456324, here are decompositions:

5 + 31456319 = 31456324
47 + 31456277 = 31456324
83 + 31456241 = 31456324
131 + 31456193 = 31456324
257 + 31456067 = 31456324
311 + 31456013 = 31456324
503 + 31455821 = 31456324
521 + 31455803 = 31456324

Showing the first eight; more decompositions exist.
