Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126426, here are decompositions:

5 + 126421 = 126426
29 + 126397 = 126426
67 + 126359 = 126426
89 + 126337 = 126426
103 + 126323 = 126426
109 + 126317 = 126426
193 + 126233 = 126426
197 + 126229 = 126426

Showing the first eight; more decompositions exist.
