Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123564, here are decompositions:

11 + 123553 = 123564
13 + 123551 = 123564
17 + 123547 = 123564
37 + 123527 = 123564
47 + 123517 = 123564
61 + 123503 = 123564
71 + 123493 = 123564
73 + 123491 = 123564

Showing the first eight; more decompositions exist.
