Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446338, here are decompositions:

97 + 31446241 = 31446338
109 + 31446229 = 31446338
127 + 31446211 = 31446338
241 + 31446097 = 31446338
271 + 31446067 = 31446338
277 + 31446061 = 31446338
307 + 31446031 = 31446338
379 + 31445959 = 31446338

Showing the first eight; more decompositions exist.
