Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126690, here are decompositions:

7 + 126683 = 126690
37 + 126653 = 126690
59 + 126631 = 126690
79 + 126611 = 126690
89 + 126601 = 126690
107 + 126583 = 126690
139 + 126551 = 126690
149 + 126541 = 126690

Showing the first eight; more decompositions exist.
