Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551096, here are decompositions:

7 + 31551089 = 31551096
29 + 31551067 = 31551096
97 + 31550999 = 31551096
103 + 31550993 = 31551096
149 + 31550947 = 31551096
173 + 31550923 = 31551096
229 + 31550867 = 31551096
263 + 31550833 = 31551096

Showing the first eight; more decompositions exist.
