Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599162, here are decompositions:

5 + 31599157 = 31599162
59 + 31599103 = 31599162
61 + 31599101 = 31599162
103 + 31599059 = 31599162
173 + 31598989 = 31599162
223 + 31598939 = 31599162
229 + 31598933 = 31599162
239 + 31598923 = 31599162

Showing the first eight; more decompositions exist.
