Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613298, here are decompositions:

7 + 31613291 = 31613298
71 + 31613227 = 31613298
107 + 31613191 = 31613298
127 + 31613171 = 31613298
179 + 31613119 = 31613298
181 + 31613117 = 31613298
191 + 31613107 = 31613298
271 + 31613027 = 31613298

Showing the first eight; more decompositions exist.
