Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126798, here are decompositions:

17 + 126781 = 126798
37 + 126761 = 126798
41 + 126757 = 126798
47 + 126751 = 126798
59 + 126739 = 126798
79 + 126719 = 126798
107 + 126691 = 126798
157 + 126641 = 126798

Showing the first eight; more decompositions exist.
