Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577022, here are decompositions:

5 + 31577017 = 31577022
13 + 31577009 = 31577022
31 + 31576991 = 31577022
73 + 31576949 = 31577022
131 + 31576891 = 31577022
179 + 31576843 = 31577022
263 + 31576759 = 31577022
271 + 31576751 = 31577022

Showing the first eight; more decompositions exist.
