Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622498, here are decompositions:

7 + 31622491 = 31622498
31 + 31622467 = 31622498
109 + 31622389 = 31622498
151 + 31622347 = 31622498
211 + 31622287 = 31622498
241 + 31622257 = 31622498
331 + 31622167 = 31622498
367 + 31622131 = 31622498

Showing the first eight; more decompositions exist.
