Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598940, here are decompositions:

7 + 31598933 = 31598940
13 + 31598927 = 31598940
17 + 31598923 = 31598940
29 + 31598911 = 31598940
31 + 31598909 = 31598940
53 + 31598887 = 31598940
67 + 31598873 = 31598940
73 + 31598867 = 31598940

Showing the first eight; more decompositions exist.
