Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551276, here are decompositions:

17 + 31551259 = 31551276
73 + 31551203 = 31551276
89 + 31551187 = 31551276
103 + 31551173 = 31551276
137 + 31551139 = 31551276
139 + 31551137 = 31551276
179 + 31551097 = 31551276
257 + 31551019 = 31551276

Showing the first eight; more decompositions exist.
