Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500264, here are decompositions:

43 + 31500221 = 31500264
67 + 31500197 = 31500264
71 + 31500193 = 31500264
151 + 31500113 = 31500264
157 + 31500107 = 31500264
163 + 31500101 = 31500264
181 + 31500083 = 31500264
241 + 31500023 = 31500264

Showing the first eight; more decompositions exist.
