Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611996, here are decompositions:

79 + 31611917 = 31611996
89 + 31611907 = 31611996
103 + 31611893 = 31611996
113 + 31611883 = 31611996
127 + 31611869 = 31611996
167 + 31611829 = 31611996
179 + 31611817 = 31611996
193 + 31611803 = 31611996

Showing the first eight; more decompositions exist.
