Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619896, here are decompositions:

47 + 31619849 = 31619896
53 + 31619843 = 31619896
89 + 31619807 = 31619896
107 + 31619789 = 31619896
137 + 31619759 = 31619896
173 + 31619723 = 31619896
179 + 31619717 = 31619896
227 + 31619669 = 31619896

Showing the first eight; more decompositions exist.
