Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619956, here are decompositions:

3 + 31619953 = 31619956
107 + 31619849 = 31619956
113 + 31619843 = 31619956
149 + 31619807 = 31619956
167 + 31619789 = 31619956
197 + 31619759 = 31619956
233 + 31619723 = 31619956
239 + 31619717 = 31619956

Showing the first eight; more decompositions exist.
