Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590982, here are decompositions:

23 + 31590959 = 31590982
41 + 31590941 = 31590982
53 + 31590929 = 31590982
83 + 31590899 = 31590982
89 + 31590893 = 31590982
149 + 31590833 = 31590982
179 + 31590803 = 31590982
191 + 31590791 = 31590982

Showing the first eight; more decompositions exist.
