Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483472, here are decompositions:

3 + 31483469 = 31483472
19 + 31483453 = 31483472
43 + 31483429 = 31483472
103 + 31483369 = 31483472
211 + 31483261 = 31483472
379 + 31483093 = 31483472
421 + 31483051 = 31483472
499 + 31482973 = 31483472

Showing the first eight; more decompositions exist.
