Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548372, here are decompositions:

29 + 31548343 = 31548372
41 + 31548331 = 31548372
59 + 31548313 = 31548372
71 + 31548301 = 31548372
73 + 31548299 = 31548372
103 + 31548269 = 31548372
109 + 31548263 = 31548372
223 + 31548149 = 31548372

Showing the first eight; more decompositions exist.
