Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143928, here are decompositions:

19 + 143909 = 143928
47 + 143881 = 143928
97 + 143831 = 143928
101 + 143827 = 143928
107 + 143821 = 143928
131 + 143797 = 143928
137 + 143791 = 143928
149 + 143779 = 143928

Showing the first eight; more decompositions exist.
