Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524048, here are decompositions:

5 + 31524043 = 31524048
37 + 31524011 = 31524048
107 + 31523941 = 31524048
109 + 31523939 = 31524048
131 + 31523917 = 31524048
167 + 31523881 = 31524048
197 + 31523851 = 31524048
379 + 31523669 = 31524048

Showing the first eight; more decompositions exist.
