Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553328, here are decompositions:

7 + 31553321 = 31553328
67 + 31553261 = 31553328
109 + 31553219 = 31553328
127 + 31553201 = 31553328
151 + 31553177 = 31553328
167 + 31553161 = 31553328
239 + 31553089 = 31553328
251 + 31553077 = 31553328

Showing the first eight; more decompositions exist.
