Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520422, here are decompositions:

5 + 31520417 = 31520422
23 + 31520399 = 31520422
29 + 31520393 = 31520422
83 + 31520339 = 31520422
113 + 31520309 = 31520422
179 + 31520243 = 31520422
251 + 31520171 = 31520422
281 + 31520141 = 31520422

Showing the first eight; more decompositions exist.
