Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553112, here are decompositions:

23 + 31553089 = 31553112
43 + 31553069 = 31553112
113 + 31552999 = 31553112
193 + 31552919 = 31553112
229 + 31552883 = 31553112
233 + 31552879 = 31553112
281 + 31552831 = 31553112
379 + 31552733 = 31553112

Showing the first eight; more decompositions exist.
