Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553148, here are decompositions:

59 + 31553089 = 31553148
71 + 31553077 = 31553148
79 + 31553069 = 31553148
127 + 31553021 = 31553148
131 + 31553017 = 31553148
149 + 31552999 = 31553148
229 + 31552919 = 31553148
241 + 31552907 = 31553148

Showing the first eight; more decompositions exist.
