Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568352, here are decompositions:

5 + 31568347 = 31568352
19 + 31568333 = 31568352
41 + 31568311 = 31568352
43 + 31568309 = 31568352
71 + 31568281 = 31568352
131 + 31568221 = 31568352
149 + 31568203 = 31568352
173 + 31568179 = 31568352

Showing the first eight; more decompositions exist.
