Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446198, here are decompositions:

31 + 31446167 = 31446198
67 + 31446131 = 31446198
97 + 31446101 = 31446198
101 + 31446097 = 31446198
131 + 31446067 = 31446198
137 + 31446061 = 31446198
167 + 31446031 = 31446198
239 + 31445959 = 31446198

Showing the first eight; more decompositions exist.
