Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483296, here are decompositions:

59 + 31483237 = 31483296
67 + 31483229 = 31483296
79 + 31483217 = 31483296
83 + 31483213 = 31483296
127 + 31483169 = 31483296
179 + 31483117 = 31483296
199 + 31483097 = 31483296
227 + 31483069 = 31483296

Showing the first eight; more decompositions exist.
