Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551074, here are decompositions:

3 + 31551071 = 31551074
7 + 31551067 = 31551074
97 + 31550977 = 31551074
127 + 31550947 = 31551074
151 + 31550923 = 31551074
223 + 31550851 = 31551074
241 + 31550833 = 31551074
271 + 31550803 = 31551074

Showing the first eight; more decompositions exist.
