Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619964, here are decompositions:

11 + 31619953 = 31619964
53 + 31619911 = 31619964
157 + 31619807 = 31619964
163 + 31619801 = 31619964
193 + 31619771 = 31619964
223 + 31619741 = 31619964
241 + 31619723 = 31619964
251 + 31619713 = 31619964

Showing the first eight; more decompositions exist.
