Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612944, here are decompositions:

5 + 31612939 = 31612944
31 + 31612913 = 31612944
53 + 31612891 = 31612944
71 + 31612873 = 31612944
113 + 31612831 = 31612944
191 + 31612753 = 31612944
197 + 31612747 = 31612944
211 + 31612733 = 31612944

Showing the first eight; more decompositions exist.
