Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483236, here are decompositions:

7 + 31483229 = 31483236
19 + 31483217 = 31483236
23 + 31483213 = 31483236
67 + 31483169 = 31483236
73 + 31483163 = 31483236
139 + 31483097 = 31483236
149 + 31483087 = 31483236
167 + 31483069 = 31483236

Showing the first eight; more decompositions exist.
