Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492716, here are decompositions:

19 + 31492697 = 31492716
53 + 31492663 = 31492716
89 + 31492627 = 31492716
113 + 31492603 = 31492716
139 + 31492577 = 31492716
149 + 31492567 = 31492716
163 + 31492553 = 31492716
179 + 31492537 = 31492716

Showing the first eight; more decompositions exist.
