Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576026, here are decompositions:

17 + 31576009 = 31576026
19 + 31576007 = 31576026
23 + 31576003 = 31576026
89 + 31575937 = 31576026
103 + 31575923 = 31576026
109 + 31575917 = 31576026
127 + 31575899 = 31576026
149 + 31575877 = 31576026

Showing the first eight; more decompositions exist.
