Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123630, here are decompositions:

11 + 123619 = 123630
29 + 123601 = 123630
37 + 123593 = 123630
47 + 123583 = 123630
79 + 123551 = 123630
83 + 123547 = 123630
103 + 123527 = 123630
113 + 123517 = 123630

Showing the first eight; more decompositions exist.
