Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124866, here are decompositions:

13 + 124853 = 124866
19 + 124847 = 124866
43 + 124823 = 124866
47 + 124819 = 124866
67 + 124799 = 124866
73 + 124793 = 124866
83 + 124783 = 124866
89 + 124777 = 124866

Showing the first eight; more decompositions exist.
