Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553214, here are decompositions:

13 + 31553201 = 31553214
31 + 31553183 = 31553214
37 + 31553177 = 31553214
53 + 31553161 = 31553214
137 + 31553077 = 31553214
151 + 31553063 = 31553214
193 + 31553021 = 31553214
197 + 31553017 = 31553214

Showing the first eight; more decompositions exist.
