Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123624, here are decompositions:

5 + 123619 = 123624
23 + 123601 = 123624
31 + 123593 = 123624
41 + 123583 = 123624
43 + 123581 = 123624
71 + 123553 = 123624
73 + 123551 = 123624
97 + 123527 = 123624

Showing the first eight; more decompositions exist.
