Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615494, here are decompositions:

5 + 31615489 = 31615494
11 + 31615483 = 31615494
17 + 31615477 = 31615494
23 + 31615471 = 31615494
103 + 31615391 = 31615494
151 + 31615343 = 31615494
173 + 31615321 = 31615494
181 + 31615313 = 31615494

Showing the first eight; more decompositions exist.
