Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553502, here are decompositions:

151 + 31553351 = 31553502
163 + 31553339 = 31553502
181 + 31553321 = 31553502
223 + 31553279 = 31553502
229 + 31553273 = 31553502
241 + 31553261 = 31553502
269 + 31553233 = 31553502
283 + 31553219 = 31553502

Showing the first eight; more decompositions exist.
