Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600996, here are decompositions:

3 + 31600993 = 31600996
113 + 31600883 = 31600996
137 + 31600859 = 31600996
173 + 31600823 = 31600996
179 + 31600817 = 31600996
197 + 31600799 = 31600996
263 + 31600733 = 31600996
293 + 31600703 = 31600996

Showing the first eight; more decompositions exist.
