Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520396, here are decompositions:

3 + 31520393 = 31520396
7 + 31520389 = 31520396
43 + 31520353 = 31520396
79 + 31520317 = 31520396
97 + 31520299 = 31520396
163 + 31520233 = 31520396
223 + 31520173 = 31520396
277 + 31520119 = 31520396

Showing the first eight; more decompositions exist.
