Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622466, here are decompositions:

37 + 31622429 = 31622466
89 + 31622377 = 31622466
97 + 31622369 = 31622466
173 + 31622293 = 31622466
179 + 31622287 = 31622466
193 + 31622273 = 31622466
229 + 31622237 = 31622466
277 + 31622189 = 31622466

Showing the first eight; more decompositions exist.
