Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483266, here are decompositions:

5 + 31483261 = 31483266
29 + 31483237 = 31483266
37 + 31483229 = 31483266
53 + 31483213 = 31483266
97 + 31483169 = 31483266
103 + 31483163 = 31483266
149 + 31483117 = 31483266
173 + 31483093 = 31483266

Showing the first eight; more decompositions exist.
