Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496268, here are decompositions:

5 + 31496263 = 31496268
7 + 31496261 = 31496268
47 + 31496221 = 31496268
59 + 31496209 = 31496268
107 + 31496161 = 31496268
127 + 31496141 = 31496268
149 + 31496119 = 31496268
211 + 31496057 = 31496268

Showing the first eight; more decompositions exist.
