Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483152, here are decompositions:

59 + 31483093 = 31483152
83 + 31483069 = 31483152
101 + 31483051 = 31483152
149 + 31483003 = 31483152
179 + 31482973 = 31483152
263 + 31482889 = 31483152
293 + 31482859 = 31483152
313 + 31482839 = 31483152

Showing the first eight; more decompositions exist.
