Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143898, here are decompositions:

17 + 143881 = 143898
19 + 143879 = 143898
67 + 143831 = 143898
71 + 143827 = 143898
101 + 143797 = 143898
107 + 143791 = 143898
179 + 143719 = 143898
199 + 143699 = 143898

Showing the first eight; more decompositions exist.
