Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496238, here are decompositions:

17 + 31496221 = 31496238
19 + 31496219 = 31496238
29 + 31496209 = 31496238
97 + 31496141 = 31496238
139 + 31496099 = 31496238
181 + 31496057 = 31496238
197 + 31496041 = 31496238
211 + 31496027 = 31496238

Showing the first eight; more decompositions exist.
