Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143958, here are decompositions:

5 + 143953 = 143958
11 + 143947 = 143958
79 + 143879 = 143958
127 + 143831 = 143958
131 + 143827 = 143958
137 + 143821 = 143958
151 + 143807 = 143958
167 + 143791 = 143958

Showing the first eight; more decompositions exist.
