Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551246, here are decompositions:

43 + 31551203 = 31551246
59 + 31551187 = 31551246
73 + 31551173 = 31551246
107 + 31551139 = 31551246
109 + 31551137 = 31551246
149 + 31551097 = 31551246
157 + 31551089 = 31551246
179 + 31551067 = 31551246

Showing the first eight; more decompositions exist.
