Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590934, here are decompositions:

3 + 31590931 = 31590934
5 + 31590929 = 31590934
17 + 31590917 = 31590934
41 + 31590893 = 31590934
47 + 31590887 = 31590934
101 + 31590833 = 31590934
131 + 31590803 = 31590934
197 + 31590737 = 31590934

Showing the first eight; more decompositions exist.
