Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619814, here are decompositions:

7 + 31619807 = 31619814
13 + 31619801 = 31619814
43 + 31619771 = 31619814
53 + 31619761 = 31619814
73 + 31619741 = 31619814
97 + 31619717 = 31619814
101 + 31619713 = 31619814
131 + 31619683 = 31619814

Showing the first eight; more decompositions exist.
