Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496208, here are decompositions:

47 + 31496161 = 31496208
67 + 31496141 = 31496208
89 + 31496119 = 31496208
109 + 31496099 = 31496208
151 + 31496057 = 31496208
167 + 31496041 = 31496208
181 + 31496027 = 31496208
197 + 31496011 = 31496208

Showing the first eight; more decompositions exist.
