Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596148, here are decompositions:

5 + 31596143 = 31596148
29 + 31596119 = 31596148
107 + 31596041 = 31596148
179 + 31595969 = 31596148
281 + 31595867 = 31596148
317 + 31595831 = 31596148
431 + 31595717 = 31596148
461 + 31595687 = 31596148

Showing the first eight; more decompositions exist.
