Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590946, here are decompositions:

3 + 31590943 = 31590946
5 + 31590941 = 31590946
17 + 31590929 = 31590946
29 + 31590917 = 31590946
47 + 31590899 = 31590946
53 + 31590893 = 31590946
59 + 31590887 = 31590946
113 + 31590833 = 31590946

Showing the first eight; more decompositions exist.
