Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622298, here are decompositions:

5 + 31622293 = 31622298
11 + 31622287 = 31622298
17 + 31622281 = 31622298
41 + 31622257 = 31622298
61 + 31622237 = 31622298
109 + 31622189 = 31622298
131 + 31622167 = 31622298
151 + 31622147 = 31622298

Showing the first eight; more decompositions exist.
