Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599150, here are decompositions:

47 + 31599103 = 31599150
197 + 31598953 = 31599150
211 + 31598939 = 31599150
223 + 31598927 = 31599150
227 + 31598923 = 31599150
239 + 31598911 = 31599150
241 + 31598909 = 31599150
263 + 31598887 = 31599150

Showing the first eight; more decompositions exist.
