Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520484, here are decompositions:

5 + 31520479 = 31520484
31 + 31520453 = 31520484
67 + 31520417 = 31520484
97 + 31520387 = 31520484
113 + 31520371 = 31520484
131 + 31520353 = 31520484
167 + 31520317 = 31520484
241 + 31520243 = 31520484

Showing the first eight; more decompositions exist.
