Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611822, here are decompositions:

5 + 31611817 = 31611822
19 + 31611803 = 31611822
61 + 31611761 = 31611822
89 + 31611733 = 31611822
103 + 31611719 = 31611822
113 + 31611709 = 31611822
149 + 31611673 = 31611822
163 + 31611659 = 31611822

Showing the first eight; more decompositions exist.
