Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622262, here are decompositions:

5 + 31622257 = 31622262
73 + 31622189 = 31622262
79 + 31622183 = 31622262
83 + 31622179 = 31622262
109 + 31622153 = 31622262
131 + 31622131 = 31622262
149 + 31622113 = 31622262
181 + 31622081 = 31622262

Showing the first eight; more decompositions exist.
