Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553332, here are decompositions:

11 + 31553321 = 31553332
53 + 31553279 = 31553332
59 + 31553273 = 31553332
71 + 31553261 = 31553332
113 + 31553219 = 31553332
131 + 31553201 = 31553332
149 + 31553183 = 31553332
263 + 31553069 = 31553332

Showing the first eight; more decompositions exist.
