Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496168, here are decompositions:

7 + 31496161 = 31496168
127 + 31496041 = 31496168
157 + 31496011 = 31496168
271 + 31495897 = 31496168
349 + 31495819 = 31496168
367 + 31495801 = 31496168
439 + 31495729 = 31496168
577 + 31495591 = 31496168

Showing the first eight; more decompositions exist.
