Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551344, here are decompositions:

3 + 31551341 = 31551344
37 + 31551307 = 31551344
61 + 31551283 = 31551344
67 + 31551277 = 31551344
157 + 31551187 = 31551344
193 + 31551151 = 31551344
277 + 31551067 = 31551344
367 + 31550977 = 31551344

Showing the first eight; more decompositions exist.
