Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143970, here are decompositions:

17 + 143953 = 143970
23 + 143947 = 143970
61 + 143909 = 143970
89 + 143881 = 143970
97 + 143873 = 143970
137 + 143833 = 143970
139 + 143831 = 143970
149 + 143821 = 143970

Showing the first eight; more decompositions exist.
