Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123648, here are decompositions:

11 + 123637 = 123648
17 + 123631 = 123648
29 + 123619 = 123648
47 + 123601 = 123648
67 + 123581 = 123648
97 + 123551 = 123648
101 + 123547 = 123648
131 + 123517 = 123648

Showing the first eight; more decompositions exist.
