Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596330, here are decompositions:

13 + 31596317 = 31596330
19 + 31596311 = 31596330
23 + 31596307 = 31596330
37 + 31596293 = 31596330
137 + 31596193 = 31596330
167 + 31596163 = 31596330
179 + 31596151 = 31596330
211 + 31596119 = 31596330

Showing the first eight; more decompositions exist.
