Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619832, here are decompositions:

11 + 31619821 = 31619832
31 + 31619801 = 31619832
43 + 31619789 = 31619832
61 + 31619771 = 31619832
71 + 31619761 = 31619832
73 + 31619759 = 31619832
109 + 31619723 = 31619832
149 + 31619683 = 31619832

Showing the first eight; more decompositions exist.
