Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483234, here are decompositions:

5 + 31483229 = 31483234
17 + 31483217 = 31483234
71 + 31483163 = 31483234
137 + 31483097 = 31483234
173 + 31483061 = 31483234
257 + 31482977 = 31483234
401 + 31482833 = 31483234
491 + 31482743 = 31483234

Showing the first eight; more decompositions exist.
