Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520022, here are decompositions:

5 + 31520017 = 31520022
11 + 31520011 = 31520022
13 + 31520009 = 31520022
71 + 31519951 = 31520022
89 + 31519933 = 31520022
103 + 31519919 = 31520022
113 + 31519909 = 31520022
179 + 31519843 = 31520022

Showing the first eight; more decompositions exist.
