Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143868, here are decompositions:

37 + 143831 = 143868
41 + 143827 = 143868
47 + 143821 = 143868
61 + 143807 = 143868
71 + 143797 = 143868
89 + 143779 = 143868
139 + 143729 = 143868
149 + 143719 = 143868

Showing the first eight; more decompositions exist.
