Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486762, here are decompositions:

11 + 31486751 = 31486762
23 + 31486739 = 31486762
29 + 31486733 = 31486762
53 + 31486709 = 31486762
101 + 31486661 = 31486762
149 + 31486613 = 31486762
191 + 31486571 = 31486762
233 + 31486529 = 31486762

Showing the first eight; more decompositions exist.
