Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124812, here are decompositions:

13 + 124799 = 124812
19 + 124793 = 124812
29 + 124783 = 124812
31 + 124781 = 124812
41 + 124771 = 124812
43 + 124769 = 124812
53 + 124759 = 124812
59 + 124753 = 124812

Showing the first eight; more decompositions exist.
