Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483482, here are decompositions:

11 + 31483471 = 31483482
13 + 31483469 = 31483482
29 + 31483453 = 31483482
53 + 31483429 = 31483482
113 + 31483369 = 31483482
131 + 31483351 = 31483482
269 + 31483213 = 31483482
313 + 31483169 = 31483482

Showing the first eight; more decompositions exist.
