Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483396, here are decompositions:

5 + 31483391 = 31483396
83 + 31483313 = 31483396
89 + 31483307 = 31483396
167 + 31483229 = 31483396
179 + 31483217 = 31483396
227 + 31483169 = 31483396
233 + 31483163 = 31483396
419 + 31482977 = 31483396

Showing the first eight; more decompositions exist.
