Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553274, here are decompositions:

13 + 31553261 = 31553274
41 + 31553233 = 31553274
61 + 31553213 = 31553274
73 + 31553201 = 31553274
97 + 31553177 = 31553274
113 + 31553161 = 31553274
197 + 31553077 = 31553274
211 + 31553063 = 31553274

Showing the first eight; more decompositions exist.
