Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483518, here are decompositions:

47 + 31483471 = 31483518
61 + 31483457 = 31483518
71 + 31483447 = 31483518
89 + 31483429 = 31483518
127 + 31483391 = 31483518
149 + 31483369 = 31483518
167 + 31483351 = 31483518
191 + 31483327 = 31483518

Showing the first eight; more decompositions exist.
