Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488252, here are decompositions:

41 + 31488211 = 31488252
151 + 31488101 = 31488252
163 + 31488089 = 31488252
181 + 31488071 = 31488252
193 + 31488059 = 31488252
199 + 31488053 = 31488252
233 + 31488019 = 31488252
239 + 31488013 = 31488252

Showing the first eight; more decompositions exist.
