Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568064, here are decompositions:

5 + 31568059 = 31568064
23 + 31568041 = 31568064
37 + 31568027 = 31568064
43 + 31568021 = 31568064
83 + 31567981 = 31568064
103 + 31567961 = 31568064
181 + 31567883 = 31568064
251 + 31567813 = 31568064

Showing the first eight; more decompositions exist.
