Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551294, here are decompositions:

11 + 31551283 = 31551294
13 + 31551281 = 31551294
17 + 31551277 = 31551294
107 + 31551187 = 31551294
157 + 31551137 = 31551294
197 + 31551097 = 31551294
223 + 31551071 = 31551294
227 + 31551067 = 31551294

Showing the first eight; more decompositions exist.
