Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553376, here are decompositions:

7 + 31553369 = 31553376
17 + 31553359 = 31553376
37 + 31553339 = 31553376
97 + 31553279 = 31553376
103 + 31553273 = 31553376
157 + 31553219 = 31553376
163 + 31553213 = 31553376
193 + 31553183 = 31553376

Showing the first eight; more decompositions exist.
