Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516344, here are decompositions:

11 + 31516333 = 31516344
17 + 31516327 = 31516344
47 + 31516297 = 31516344
103 + 31516241 = 31516344
107 + 31516237 = 31516344
191 + 31516153 = 31516344
241 + 31516103 = 31516344
257 + 31516087 = 31516344

Showing the first eight; more decompositions exist.
