Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596012, here are decompositions:

5 + 31596007 = 31596012
23 + 31595989 = 31596012
29 + 31595983 = 31596012
43 + 31595969 = 31596012
83 + 31595929 = 31596012
131 + 31595881 = 31596012
139 + 31595873 = 31596012
179 + 31595833 = 31596012

Showing the first eight; more decompositions exist.
