Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550462, here are decompositions:

3 + 31550459 = 31550462
61 + 31550401 = 31550462
109 + 31550353 = 31550462
211 + 31550251 = 31550462
241 + 31550221 = 31550462
283 + 31550179 = 31550462
313 + 31550149 = 31550462
331 + 31550131 = 31550462

Showing the first eight; more decompositions exist.
