Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559862, here are decompositions:

11 + 31559851 = 31559862
13 + 31559849 = 31559862
29 + 31559833 = 31559862
31 + 31559831 = 31559862
41 + 31559821 = 31559862
53 + 31559809 = 31559862
79 + 31559783 = 31559862
163 + 31559699 = 31559862

Showing the first eight; more decompositions exist.
