Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533952, here are decompositions:

3 + 31533949 = 31533952
29 + 31533923 = 31533952
41 + 31533911 = 31533952
113 + 31533839 = 31533952
179 + 31533773 = 31533952
293 + 31533659 = 31533952
311 + 31533641 = 31533952
353 + 31533599 = 31533952

Showing the first eight; more decompositions exist.
