Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126722, here are decompositions:

3 + 126719 = 126722
19 + 126703 = 126722
31 + 126691 = 126722
109 + 126613 = 126722
139 + 126583 = 126722
181 + 126541 = 126722
223 + 126499 = 126722
229 + 126493 = 126722

Showing the first eight; more decompositions exist.
