Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568324, here are decompositions:

13 + 31568311 = 31568324
37 + 31568287 = 31568324
43 + 31568281 = 31568324
97 + 31568227 = 31568324
103 + 31568221 = 31568324
127 + 31568197 = 31568324
241 + 31568083 = 31568324
283 + 31568041 = 31568324

Showing the first eight; more decompositions exist.
