Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516452, here are decompositions:

29 + 31516423 = 31516452
41 + 31516411 = 31516452
73 + 31516379 = 31516452
199 + 31516253 = 31516452
211 + 31516241 = 31516452
251 + 31516201 = 31516452
263 + 31516189 = 31516452
269 + 31516183 = 31516452

Showing the first eight; more decompositions exist.
