Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622618, here are decompositions:

19 + 31622599 = 31622618
109 + 31622509 = 31622618
127 + 31622491 = 31622618
151 + 31622467 = 31622618
229 + 31622389 = 31622618
241 + 31622377 = 31622618
271 + 31622347 = 31622618
331 + 31622287 = 31622618

Showing the first eight; more decompositions exist.
