Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488324, here are decompositions:

31 + 31488293 = 31488324
53 + 31488271 = 31488324
67 + 31488257 = 31488324
97 + 31488227 = 31488324
113 + 31488211 = 31488324
163 + 31488161 = 31488324
191 + 31488133 = 31488324
223 + 31488101 = 31488324

Showing the first eight; more decompositions exist.
