Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522740, here are decompositions:

23 + 31522717 = 31522740
47 + 31522693 = 31522740
71 + 31522669 = 31522740
83 + 31522657 = 31522740
107 + 31522633 = 31522740
127 + 31522613 = 31522740
149 + 31522591 = 31522740
157 + 31522583 = 31522740

Showing the first eight; more decompositions exist.
