Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599330, here are decompositions:

17 + 31599313 = 31599330
23 + 31599307 = 31599330
71 + 31599259 = 31599330
83 + 31599247 = 31599330
137 + 31599193 = 31599330
157 + 31599173 = 31599330
173 + 31599157 = 31599330
227 + 31599103 = 31599330

Showing the first eight; more decompositions exist.
