Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622898, here are decompositions:

5 + 31622893 = 31622898
17 + 31622881 = 31622898
61 + 31622837 = 31622898
89 + 31622809 = 31622898
157 + 31622741 = 31622898
199 + 31622699 = 31622898
211 + 31622687 = 31622898
227 + 31622671 = 31622898

Showing the first eight; more decompositions exist.
