Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143982, here are decompositions:

5 + 143977 = 143982
11 + 143971 = 143982
29 + 143953 = 143982
73 + 143909 = 143982
101 + 143881 = 143982
103 + 143879 = 143982
109 + 143873 = 143982
149 + 143833 = 143982

Showing the first eight; more decompositions exist.
