Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596072, here are decompositions:

5 + 31596067 = 31596072
23 + 31596049 = 31596072
31 + 31596041 = 31596072
43 + 31596029 = 31596072
83 + 31595989 = 31596072
89 + 31595983 = 31596072
103 + 31595969 = 31596072
191 + 31595881 = 31596072

Showing the first eight; more decompositions exist.
