Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600032, here are decompositions:

31 + 31600001 = 31600032
73 + 31599959 = 31600032
103 + 31599929 = 31600032
131 + 31599901 = 31600032
173 + 31599859 = 31600032
223 + 31599809 = 31600032
251 + 31599781 = 31600032
271 + 31599761 = 31600032

Showing the first eight; more decompositions exist.
