Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523760, here are decompositions:

7 + 31523753 = 31523760
11 + 31523749 = 31523760
53 + 31523707 = 31523760
101 + 31523659 = 31523760
109 + 31523651 = 31523760
113 + 31523647 = 31523760
127 + 31523633 = 31523760
181 + 31523579 = 31523760

Showing the first eight; more decompositions exist.
