Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593330, here are decompositions:

17 + 31593313 = 31593330
23 + 31593307 = 31593330
31 + 31593299 = 31593330
79 + 31593251 = 31593330
137 + 31593193 = 31593330
157 + 31593173 = 31593330
233 + 31593097 = 31593330
283 + 31593047 = 31593330

Showing the first eight; more decompositions exist.
