Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619796, here are decompositions:

7 + 31619789 = 31619796
37 + 31619759 = 31619796
73 + 31619723 = 31619796
79 + 31619717 = 31619796
83 + 31619713 = 31619796
113 + 31619683 = 31619796
127 + 31619669 = 31619796
149 + 31619647 = 31619796

Showing the first eight; more decompositions exist.
