Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124722, here are decompositions:

5 + 124717 = 124722
19 + 124703 = 124722
23 + 124699 = 124722
29 + 124693 = 124722
43 + 124679 = 124722
53 + 124669 = 124722
79 + 124643 = 124722
89 + 124633 = 124722

Showing the first eight; more decompositions exist.
