Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516496, here are decompositions:

3 + 31516493 = 31516496
13 + 31516483 = 31516496
73 + 31516423 = 31516496
139 + 31516357 = 31516496
163 + 31516333 = 31516496
199 + 31516297 = 31516496
307 + 31516189 = 31516496
313 + 31516183 = 31516496

Showing the first eight; more decompositions exist.
