Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523372, here are decompositions:

43 + 31523329 = 31523372
79 + 31523293 = 31523372
151 + 31523221 = 31523372
163 + 31523209 = 31523372
211 + 31523161 = 31523372
229 + 31523143 = 31523372
241 + 31523131 = 31523372
421 + 31522951 = 31523372

Showing the first eight; more decompositions exist.
