Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522198, here are decompositions:

17 + 31522181 = 31522198
107 + 31522091 = 31522198
137 + 31522061 = 31522198
179 + 31522019 = 31522198
311 + 31521887 = 31522198
347 + 31521851 = 31522198
557 + 31521641 = 31522198
599 + 31521599 = 31522198

Showing the first eight; more decompositions exist.
