Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516422, here are decompositions:

11 + 31516411 = 31516422
43 + 31516379 = 31516422
61 + 31516361 = 31516422
89 + 31516333 = 31516422
103 + 31516319 = 31516422
181 + 31516241 = 31516422
233 + 31516189 = 31516422
239 + 31516183 = 31516422

Showing the first eight; more decompositions exist.
