Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120918, here are decompositions:

11 + 120907 = 120918
19 + 120899 = 120918
29 + 120889 = 120918
41 + 120877 = 120918
47 + 120871 = 120918
67 + 120851 = 120918
71 + 120847 = 120918
89 + 120829 = 120918

Showing the first eight; more decompositions exist.
