Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516364, here are decompositions:

3 + 31516361 = 31516364
7 + 31516357 = 31516364
31 + 31516333 = 31516364
37 + 31516327 = 31516364
67 + 31516297 = 31516364
127 + 31516237 = 31516364
163 + 31516201 = 31516364
181 + 31516183 = 31516364

Showing the first eight; more decompositions exist.
