Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126724, here are decompositions:

5 + 126719 = 126724
11 + 126713 = 126724
41 + 126683 = 126724
71 + 126653 = 126724
83 + 126641 = 126724
113 + 126611 = 126724
173 + 126551 = 126724
233 + 126491 = 126724

Showing the first eight; more decompositions exist.
