Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619922, here are decompositions:

11 + 31619911 = 31619922
53 + 31619869 = 31619922
73 + 31619849 = 31619922
79 + 31619843 = 31619922
101 + 31619821 = 31619922
151 + 31619771 = 31619922
163 + 31619759 = 31619922
181 + 31619741 = 31619922

Showing the first eight; more decompositions exist.
