Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622374, here are decompositions:

5 + 31622369 = 31622374
101 + 31622273 = 31622374
137 + 31622237 = 31622374
167 + 31622207 = 31622374
191 + 31622183 = 31622374
227 + 31622147 = 31622374
233 + 31622141 = 31622374
293 + 31622081 = 31622374

Showing the first eight; more decompositions exist.
