Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622982, here are decompositions:

23 + 31622959 = 31622982
31 + 31622951 = 31622982
43 + 31622939 = 31622982
59 + 31622923 = 31622982
89 + 31622893 = 31622982
101 + 31622881 = 31622982
173 + 31622809 = 31622982
179 + 31622803 = 31622982

Showing the first eight; more decompositions exist.
