Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590948, here are decompositions:

5 + 31590943 = 31590948
7 + 31590941 = 31590948
17 + 31590931 = 31590948
19 + 31590929 = 31590948
31 + 31590917 = 31590948
41 + 31590907 = 31590948
61 + 31590887 = 31590948
71 + 31590877 = 31590948

Showing the first eight; more decompositions exist.
