Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126744, here are decompositions:

5 + 126739 = 126744
11 + 126733 = 126744
31 + 126713 = 126744
41 + 126703 = 126744
53 + 126691 = 126744
61 + 126683 = 126744
103 + 126641 = 126744
113 + 126631 = 126744

Showing the first eight; more decompositions exist.
