Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596078, here are decompositions:

11 + 31596067 = 31596078
29 + 31596049 = 31596078
37 + 31596041 = 31596078
71 + 31596007 = 31596078
89 + 31595989 = 31596078
109 + 31595969 = 31596078
149 + 31595929 = 31596078
197 + 31595881 = 31596078

Showing the first eight; more decompositions exist.
