Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619914, here are decompositions:

3 + 31619911 = 31619914
71 + 31619843 = 31619914
107 + 31619807 = 31619914
113 + 31619801 = 31619914
173 + 31619741 = 31619914
191 + 31619723 = 31619914
197 + 31619717 = 31619914
311 + 31619603 = 31619914

Showing the first eight; more decompositions exist.
