Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123612, here are decompositions:

11 + 123601 = 123612
19 + 123593 = 123612
29 + 123583 = 123612
31 + 123581 = 123612
59 + 123553 = 123612
61 + 123551 = 123612
109 + 123503 = 123612
113 + 123499 = 123612

Showing the first eight; more decompositions exist.
