Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622398, here are decompositions:

29 + 31622369 = 31622398
191 + 31622207 = 31622398
251 + 31622147 = 31622398
257 + 31622141 = 31622398
317 + 31622081 = 31622398
419 + 31621979 = 31622398
449 + 31621949 = 31622398
659 + 31621739 = 31622398

Showing the first eight; more decompositions exist.
