Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553266, here are decompositions:

5 + 31553261 = 31553266
47 + 31553219 = 31553266
53 + 31553213 = 31553266
83 + 31553183 = 31553266
89 + 31553177 = 31553266
197 + 31553069 = 31553266
347 + 31552919 = 31553266
359 + 31552907 = 31553266

Showing the first eight; more decompositions exist.
