Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551176, here are decompositions:

3 + 31551173 = 31551176
37 + 31551139 = 31551176
79 + 31551097 = 31551176
109 + 31551067 = 31551176
157 + 31551019 = 31551176
199 + 31550977 = 31551176
229 + 31550947 = 31551176
373 + 31550803 = 31551176

Showing the first eight; more decompositions exist.
