Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553316, here are decompositions:

37 + 31553279 = 31553316
43 + 31553273 = 31553316
83 + 31553233 = 31553316
97 + 31553219 = 31553316
103 + 31553213 = 31553316
139 + 31553177 = 31553316
227 + 31553089 = 31553316
239 + 31553077 = 31553316

Showing the first eight; more decompositions exist.
