Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483550, here are decompositions:

3 + 31483547 = 31483550
79 + 31483471 = 31483550
97 + 31483453 = 31483550
103 + 31483447 = 31483550
181 + 31483369 = 31483550
199 + 31483351 = 31483550
223 + 31483327 = 31483550
313 + 31483237 = 31483550

Showing the first eight; more decompositions exist.
