Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553070, here are decompositions:

7 + 31553063 = 31553070
53 + 31553017 = 31553070
71 + 31552999 = 31553070
127 + 31552943 = 31553070
151 + 31552919 = 31553070
163 + 31552907 = 31553070
179 + 31552891 = 31553070
191 + 31552879 = 31553070

Showing the first eight; more decompositions exist.
