Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520466, here are decompositions:

13 + 31520453 = 31520466
59 + 31520407 = 31520466
67 + 31520399 = 31520466
73 + 31520393 = 31520466
79 + 31520387 = 31520466
113 + 31520353 = 31520466
127 + 31520339 = 31520466
149 + 31520317 = 31520466

Showing the first eight; more decompositions exist.
