Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553016, here are decompositions:

17 + 31552999 = 31553016
73 + 31552943 = 31553016
97 + 31552919 = 31553016
109 + 31552907 = 31553016
137 + 31552879 = 31553016
163 + 31552853 = 31553016
199 + 31552817 = 31553016
269 + 31552747 = 31553016

Showing the first eight; more decompositions exist.
