Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124518, here are decompositions:

5 + 124513 = 124518
29 + 124489 = 124518
41 + 124477 = 124518
47 + 124471 = 124518
59 + 124459 = 124518
71 + 124447 = 124518
89 + 124429 = 124518
151 + 124367 = 124518

Showing the first eight; more decompositions exist.
