Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553064, here are decompositions:

43 + 31553021 = 31553064
47 + 31553017 = 31553064
157 + 31552907 = 31553064
173 + 31552891 = 31553064
181 + 31552883 = 31553064
211 + 31552853 = 31553064
233 + 31552831 = 31553064
317 + 31552747 = 31553064

Showing the first eight; more decompositions exist.
