Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560948, here are decompositions:

5 + 31560943 = 31560948
7 + 31560941 = 31560948
37 + 31560911 = 31560948
47 + 31560901 = 31560948
61 + 31560887 = 31560948
79 + 31560869 = 31560948
101 + 31560847 = 31560948
149 + 31560799 = 31560948

Showing the first eight; more decompositions exist.
