Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452204, here are decompositions:

5 + 31452199 = 31452204
23 + 31452181 = 31452204
31 + 31452173 = 31452204
67 + 31452137 = 31452204
73 + 31452131 = 31452204
83 + 31452121 = 31452204
107 + 31452097 = 31452204
163 + 31452041 = 31452204

Showing the first eight; more decompositions exist.
