Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553190, here are decompositions:

7 + 31553183 = 31553190
13 + 31553177 = 31553190
29 + 31553161 = 31553190
101 + 31553089 = 31553190
113 + 31553077 = 31553190
127 + 31553063 = 31553190
173 + 31553017 = 31553190
191 + 31552999 = 31553190

Showing the first eight; more decompositions exist.
