Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609006, here are decompositions:

47 + 31608959 = 31609006
53 + 31608953 = 31609006
89 + 31608917 = 31609006
113 + 31608893 = 31609006
227 + 31608779 = 31609006
257 + 31608749 = 31609006
269 + 31608737 = 31609006
293 + 31608713 = 31609006

Showing the first eight; more decompositions exist.
