Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126660, here are decompositions:

7 + 126653 = 126660
19 + 126641 = 126660
29 + 126631 = 126660
47 + 126613 = 126660
59 + 126601 = 126660
109 + 126551 = 126660
113 + 126547 = 126660
167 + 126493 = 126660

Showing the first eight; more decompositions exist.
