Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126648, here are decompositions:

7 + 126641 = 126648
17 + 126631 = 126648
37 + 126611 = 126648
47 + 126601 = 126648
97 + 126551 = 126648
101 + 126547 = 126648
107 + 126541 = 126648
131 + 126517 = 126648

Showing the first eight; more decompositions exist.
