Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523934, here are decompositions:

17 + 31523917 = 31523934
53 + 31523881 = 31523934
83 + 31523851 = 31523934
131 + 31523803 = 31523934
173 + 31523761 = 31523934
181 + 31523753 = 31523934
227 + 31523707 = 31523934
283 + 31523651 = 31523934

Showing the first eight; more decompositions exist.
