Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126366, here are decompositions:

7 + 126359 = 126366
17 + 126349 = 126366
29 + 126337 = 126366
43 + 126323 = 126366
59 + 126307 = 126366
109 + 126257 = 126366
137 + 126229 = 126366
139 + 126227 = 126366

Showing the first eight; more decompositions exist.
