Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622316, here are decompositions:

23 + 31622293 = 31622316
29 + 31622287 = 31622316
43 + 31622273 = 31622316
59 + 31622257 = 31622316
79 + 31622237 = 31622316
109 + 31622207 = 31622316
127 + 31622189 = 31622316
137 + 31622179 = 31622316

Showing the first eight; more decompositions exist.
