Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619950, here are decompositions:

101 + 31619849 = 31619950
107 + 31619843 = 31619950
149 + 31619801 = 31619950
179 + 31619771 = 31619950
191 + 31619759 = 31619950
227 + 31619723 = 31619950
233 + 31619717 = 31619950
281 + 31619669 = 31619950

Showing the first eight; more decompositions exist.
