Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622338, here are decompositions:

101 + 31622237 = 31622338
131 + 31622207 = 31622338
149 + 31622189 = 31622338
191 + 31622147 = 31622338
197 + 31622141 = 31622338
257 + 31622081 = 31622338
359 + 31621979 = 31622338
389 + 31621949 = 31622338

Showing the first eight; more decompositions exist.
