Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553196, here are decompositions:

13 + 31553183 = 31553196
19 + 31553177 = 31553196
107 + 31553089 = 31553196
127 + 31553069 = 31553196
179 + 31553017 = 31553196
197 + 31552999 = 31553196
277 + 31552919 = 31553196
313 + 31552883 = 31553196

Showing the first eight; more decompositions exist.
