Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452196, here are decompositions:

23 + 31452173 = 31452196
59 + 31452137 = 31452196
107 + 31452089 = 31452196
197 + 31451999 = 31452196
227 + 31451969 = 31452196
359 + 31451837 = 31452196
389 + 31451807 = 31452196
443 + 31451753 = 31452196

Showing the first eight; more decompositions exist.
