Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460862, here are decompositions:

11 + 31460851 = 31460862
23 + 31460839 = 31460862
29 + 31460833 = 31460862
31 + 31460831 = 31460862
53 + 31460809 = 31460862
71 + 31460791 = 31460862
79 + 31460783 = 31460862
281 + 31460581 = 31460862

Showing the first eight; more decompositions exist.
