Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483762, here are decompositions:

3 + 31483759 = 31483762
29 + 31483733 = 31483762
71 + 31483691 = 31483762
113 + 31483649 = 31483762
179 + 31483583 = 31483762
269 + 31483493 = 31483762
293 + 31483469 = 31483762
449 + 31483313 = 31483762

Showing the first eight; more decompositions exist.
