Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126876, here are decompositions:

17 + 126859 = 126876
19 + 126857 = 126876
37 + 126839 = 126876
53 + 126823 = 126876
137 + 126739 = 126876
157 + 126719 = 126876
163 + 126713 = 126876
173 + 126703 = 126876

Showing the first eight; more decompositions exist.
