Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619934, here are decompositions:

23 + 31619911 = 31619934
113 + 31619821 = 31619934
127 + 31619807 = 31619934
163 + 31619771 = 31619934
173 + 31619761 = 31619934
193 + 31619741 = 31619934
211 + 31619723 = 31619934
251 + 31619683 = 31619934

Showing the first eight; more decompositions exist.
