Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612494, here are decompositions:

7 + 31612487 = 31612494
13 + 31612481 = 31612494
41 + 31612453 = 31612494
71 + 31612423 = 31612494
103 + 31612391 = 31612494
113 + 31612381 = 31612494
131 + 31612363 = 31612494
181 + 31612313 = 31612494

Showing the first eight; more decompositions exist.
