Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143964, here are decompositions:

11 + 143953 = 143964
17 + 143947 = 143964
83 + 143881 = 143964
131 + 143833 = 143964
137 + 143827 = 143964
151 + 143813 = 143964
157 + 143807 = 143964
167 + 143797 = 143964

Showing the first eight; more decompositions exist.
