Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598946, here are decompositions:

7 + 31598939 = 31598946
13 + 31598933 = 31598946
19 + 31598927 = 31598946
23 + 31598923 = 31598946
37 + 31598909 = 31598946
59 + 31598887 = 31598946
73 + 31598873 = 31598946
79 + 31598867 = 31598946

Showing the first eight; more decompositions exist.
