Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596860, here are decompositions:

3 + 31596857 = 31596860
13 + 31596847 = 31596860
67 + 31596793 = 31596860
103 + 31596757 = 31596860
109 + 31596751 = 31596860
151 + 31596709 = 31596860
181 + 31596679 = 31596860
199 + 31596661 = 31596860

Showing the first eight; more decompositions exist.
