Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619824, here are decompositions:

3 + 31619821 = 31619824
17 + 31619807 = 31619824
23 + 31619801 = 31619824
53 + 31619771 = 31619824
83 + 31619741 = 31619824
101 + 31619723 = 31619824
107 + 31619717 = 31619824
263 + 31619561 = 31619824

Showing the first eight; more decompositions exist.
