Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144978, here are decompositions:

5 + 144973 = 144978
11 + 144967 = 144978
17 + 144961 = 144978
37 + 144941 = 144978
47 + 144931 = 144978
61 + 144917 = 144978
79 + 144899 = 144978
89 + 144889 = 144978

Showing the first eight; more decompositions exist.
