Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146940, here are decompositions:

7 + 146933 = 146940
19 + 146921 = 146940
23 + 146917 = 146940
47 + 146893 = 146940
83 + 146857 = 146940
97 + 146843 = 146940
103 + 146837 = 146940
107 + 146833 = 146940

Showing the first eight; more decompositions exist.
