Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599356, here are decompositions:

3 + 31599353 = 31599356
7 + 31599349 = 31599356
43 + 31599313 = 31599356
97 + 31599259 = 31599356
109 + 31599247 = 31599356
163 + 31599193 = 31599356
199 + 31599157 = 31599356
367 + 31598989 = 31599356

Showing the first eight; more decompositions exist.
