Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126450, here are decompositions:

7 + 126443 = 126450
17 + 126433 = 126450
29 + 126421 = 126450
53 + 126397 = 126450
101 + 126349 = 126450
109 + 126341 = 126450
113 + 126337 = 126450
127 + 126323 = 126450

Showing the first eight; more decompositions exist.
