Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483440, here are decompositions:

7 + 31483433 = 31483440
11 + 31483429 = 31483440
71 + 31483369 = 31483440
89 + 31483351 = 31483440
113 + 31483327 = 31483440
127 + 31483313 = 31483440
179 + 31483261 = 31483440
211 + 31483229 = 31483440

Showing the first eight; more decompositions exist.
