Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486822, here are decompositions:

53 + 31486769 = 31486822
71 + 31486751 = 31486822
83 + 31486739 = 31486822
89 + 31486733 = 31486822
113 + 31486709 = 31486822
179 + 31486643 = 31486822
251 + 31486571 = 31486822
293 + 31486529 = 31486822

Showing the first eight; more decompositions exist.
