Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447822, here are decompositions:

11 + 31447811 = 31447822
23 + 31447799 = 31447822
53 + 31447769 = 31447822
71 + 31447751 = 31447822
149 + 31447673 = 31447822
179 + 31447643 = 31447822
191 + 31447631 = 31447822
239 + 31447583 = 31447822

Showing the first eight; more decompositions exist.
