Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612044, here are decompositions:

31 + 31612013 = 31612044
47 + 31611997 = 31612044
103 + 31611941 = 31612044
127 + 31611917 = 31612044
137 + 31611907 = 31612044
151 + 31611893 = 31612044
193 + 31611851 = 31612044
227 + 31611817 = 31612044

Showing the first eight; more decompositions exist.
