Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149778, here are decompositions:

7 + 149771 = 149778
11 + 149767 = 149778
19 + 149759 = 149778
29 + 149749 = 149778
47 + 149731 = 149778
61 + 149717 = 149778
67 + 149711 = 149778
89 + 149689 = 149778

Showing the first eight; more decompositions exist.
