Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609326, here are decompositions:

37 + 31609289 = 31609326
59 + 31609267 = 31609326
97 + 31609229 = 31609326
103 + 31609223 = 31609326
113 + 31609213 = 31609326
137 + 31609189 = 31609326
233 + 31609093 = 31609326
239 + 31609087 = 31609326

Showing the first eight; more decompositions exist.
