Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446252, here are decompositions:

11 + 31446241 = 31446252
23 + 31446229 = 31446252
29 + 31446223 = 31446252
41 + 31446211 = 31446252
151 + 31446101 = 31446252
191 + 31446061 = 31446252
199 + 31446053 = 31446252
241 + 31446011 = 31446252

Showing the first eight; more decompositions exist.
