Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504168, here are decompositions:

41 + 31504127 = 31504168
71 + 31504097 = 31504168
131 + 31504037 = 31504168
191 + 31503977 = 31504168
197 + 31503971 = 31504168
239 + 31503929 = 31504168
251 + 31503917 = 31504168
257 + 31503911 = 31504168

Showing the first eight; more decompositions exist.
