Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483356, here are decompositions:

5 + 31483351 = 31483356
29 + 31483327 = 31483356
43 + 31483313 = 31483356
127 + 31483229 = 31483356
139 + 31483217 = 31483356
193 + 31483163 = 31483356
239 + 31483117 = 31483356
263 + 31483093 = 31483356

Showing the first eight; more decompositions exist.
