Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553124, here are decompositions:

47 + 31553077 = 31553124
61 + 31553063 = 31553124
103 + 31553021 = 31553124
107 + 31553017 = 31553124
181 + 31552943 = 31553124
233 + 31552891 = 31553124
241 + 31552883 = 31553124
271 + 31552853 = 31553124

Showing the first eight; more decompositions exist.
