Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622382, here are decompositions:

5 + 31622377 = 31622382
13 + 31622369 = 31622382
89 + 31622293 = 31622382
101 + 31622281 = 31622382
109 + 31622273 = 31622382
193 + 31622189 = 31622382
199 + 31622183 = 31622382
229 + 31622153 = 31622382

Showing the first eight; more decompositions exist.
