Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143816, here are decompositions:

3 + 143813 = 143816
19 + 143797 = 143816
37 + 143779 = 143816
73 + 143743 = 143816
97 + 143719 = 143816
139 + 143677 = 143816
163 + 143653 = 143816
199 + 143617 = 143816

Showing the first eight; more decompositions exist.
