Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553198, here are decompositions:

37 + 31553161 = 31553198
109 + 31553089 = 31553198
181 + 31553017 = 31553198
199 + 31552999 = 31553198
307 + 31552891 = 31553198
367 + 31552831 = 31553198
577 + 31552621 = 31553198
619 + 31552579 = 31553198

Showing the first eight; more decompositions exist.
