Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622194, here are decompositions:

5 + 31622189 = 31622194
11 + 31622183 = 31622194
41 + 31622153 = 31622194
47 + 31622147 = 31622194
53 + 31622141 = 31622194
113 + 31622081 = 31622194
293 + 31621901 = 31622194
347 + 31621847 = 31622194

Showing the first eight; more decompositions exist.
