Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126438, here are decompositions:

5 + 126433 = 126438
17 + 126421 = 126438
41 + 126397 = 126438
79 + 126359 = 126438
89 + 126349 = 126438
97 + 126341 = 126438
101 + 126337 = 126438
127 + 126311 = 126438

Showing the first eight; more decompositions exist.
