Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593948, here are decompositions:

5 + 31593943 = 31593948
11 + 31593937 = 31593948
17 + 31593931 = 31593948
47 + 31593901 = 31593948
79 + 31593869 = 31593948
109 + 31593839 = 31593948
151 + 31593797 = 31593948
181 + 31593767 = 31593948

Showing the first eight; more decompositions exist.
