Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126630, here are decompositions:

17 + 126613 = 126630
19 + 126611 = 126630
29 + 126601 = 126630
47 + 126583 = 126630
79 + 126551 = 126630
83 + 126547 = 126630
89 + 126541 = 126630
113 + 126517 = 126630

Showing the first eight; more decompositions exist.
