Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537068, here are decompositions:

19 + 31537049 = 31537068
29 + 31537039 = 31537068
41 + 31537027 = 31537068
67 + 31537001 = 31537068
109 + 31536959 = 31537068
131 + 31536937 = 31537068
151 + 31536917 = 31537068
197 + 31536871 = 31537068

Showing the first eight; more decompositions exist.
