Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537110, here are decompositions:

13 + 31537097 = 31537110
23 + 31537087 = 31537110
61 + 31537049 = 31537110
67 + 31537043 = 31537110
71 + 31537039 = 31537110
83 + 31537027 = 31537110
107 + 31537003 = 31537110
109 + 31537001 = 31537110

Showing the first eight; more decompositions exist.
