Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560798, here are decompositions:

7 + 31560791 = 31560798
41 + 31560757 = 31560798
47 + 31560751 = 31560798
67 + 31560731 = 31560798
79 + 31560719 = 31560798
89 + 31560709 = 31560798
109 + 31560689 = 31560798
151 + 31560647 = 31560798

Showing the first eight; more decompositions exist.
