Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619848, here are decompositions:

5 + 31619843 = 31619848
41 + 31619807 = 31619848
47 + 31619801 = 31619848
59 + 31619789 = 31619848
89 + 31619759 = 31619848
107 + 31619741 = 31619848
131 + 31619717 = 31619848
179 + 31619669 = 31619848

Showing the first eight; more decompositions exist.
