Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143886, here are decompositions:

5 + 143881 = 143886
7 + 143879 = 143886
13 + 143873 = 143886
53 + 143833 = 143886
59 + 143827 = 143886
73 + 143813 = 143886
79 + 143807 = 143886
89 + 143797 = 143886

Showing the first eight; more decompositions exist.
