Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480032, here are decompositions:

11 + 31480021 = 31480032
13 + 31480019 = 31480032
71 + 31479961 = 31480032
83 + 31479949 = 31480032
151 + 31479881 = 31480032
211 + 31479821 = 31480032
229 + 31479803 = 31480032
239 + 31479793 = 31480032

Showing the first eight; more decompositions exist.
