Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126732, here are decompositions:

13 + 126719 = 126732
19 + 126713 = 126732
29 + 126703 = 126732
41 + 126691 = 126732
79 + 126653 = 126732
101 + 126631 = 126732
131 + 126601 = 126732
149 + 126583 = 126732

Showing the first eight; more decompositions exist.
