Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553010, here are decompositions:

11 + 31552999 = 31553010
67 + 31552943 = 31553010
103 + 31552907 = 31553010
127 + 31552883 = 31553010
131 + 31552879 = 31553010
157 + 31552853 = 31553010
163 + 31552847 = 31553010
179 + 31552831 = 31553010

Showing the first eight; more decompositions exist.
