Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483216, here are decompositions:

3 + 31483213 = 31483216
47 + 31483169 = 31483216
53 + 31483163 = 31483216
239 + 31482977 = 31483216
269 + 31482947 = 31483216
383 + 31482833 = 31483216
509 + 31482707 = 31483216
599 + 31482617 = 31483216

Showing the first eight; more decompositions exist.
