Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553106, here are decompositions:

17 + 31553089 = 31553106
29 + 31553077 = 31553106
37 + 31553069 = 31553106
43 + 31553063 = 31553106
89 + 31553017 = 31553106
107 + 31552999 = 31553106
163 + 31552943 = 31553106
199 + 31552907 = 31553106

Showing the first eight; more decompositions exist.
