Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474422, here are decompositions:

19 + 31474403 = 31474422
59 + 31474363 = 31474422
71 + 31474351 = 31474422
79 + 31474343 = 31474422
103 + 31474319 = 31474422
131 + 31474291 = 31474422
173 + 31474249 = 31474422
251 + 31474171 = 31474422

Showing the first eight; more decompositions exist.
