Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483808, here are decompositions:

7 + 31483801 = 31483808
19 + 31483789 = 31483808
211 + 31483597 = 31483808
337 + 31483471 = 31483808
379 + 31483429 = 31483808
439 + 31483369 = 31483808
457 + 31483351 = 31483808
547 + 31483261 = 31483808

Showing the first eight; more decompositions exist.
