Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552010, here are decompositions:

13 + 31551997 = 31552010
31 + 31551979 = 31552010
73 + 31551937 = 31552010
109 + 31551901 = 31552010
151 + 31551859 = 31552010
157 + 31551853 = 31552010
229 + 31551781 = 31552010
277 + 31551733 = 31552010

Showing the first eight; more decompositions exist.
