Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568034, here are decompositions:

7 + 31568027 = 31568034
13 + 31568021 = 31568034
53 + 31567981 = 31568034
73 + 31567961 = 31568034
103 + 31567931 = 31568034
151 + 31567883 = 31568034
293 + 31567741 = 31568034
317 + 31567717 = 31568034

Showing the first eight; more decompositions exist.
