Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122940, here are decompositions:

11 + 122929 = 122940
19 + 122921 = 122940
53 + 122887 = 122940
71 + 122869 = 122940
73 + 122867 = 122940
79 + 122861 = 122940
101 + 122839 = 122940
107 + 122833 = 122940

Showing the first eight; more decompositions exist.
