Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126726, here are decompositions:

7 + 126719 = 126726
13 + 126713 = 126726
23 + 126703 = 126726
43 + 126683 = 126726
73 + 126653 = 126726
113 + 126613 = 126726
179 + 126547 = 126726
227 + 126499 = 126726

Showing the first eight; more decompositions exist.
