Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622286, here are decompositions:

5 + 31622281 = 31622286
13 + 31622273 = 31622286
29 + 31622257 = 31622286
79 + 31622207 = 31622286
97 + 31622189 = 31622286
103 + 31622183 = 31622286
107 + 31622179 = 31622286
139 + 31622147 = 31622286

Showing the first eight; more decompositions exist.
