Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126746, here are decompositions:

3 + 126743 = 126746
7 + 126739 = 126746
13 + 126733 = 126746
43 + 126703 = 126746
163 + 126583 = 126746
199 + 126547 = 126746
229 + 126517 = 126746
313 + 126433 = 126746

Showing the first eight; more decompositions exist.
