Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596042, here are decompositions:

13 + 31596029 = 31596042
53 + 31595989 = 31596042
59 + 31595983 = 31596042
73 + 31595969 = 31596042
113 + 31595929 = 31596042
173 + 31595869 = 31596042
211 + 31595831 = 31596042
271 + 31595771 = 31596042

Showing the first eight; more decompositions exist.
