Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143940, here are decompositions:

31 + 143909 = 143940
59 + 143881 = 143940
61 + 143879 = 143940
67 + 143873 = 143940
107 + 143833 = 143940
109 + 143831 = 143940
113 + 143827 = 143940
127 + 143813 = 143940

Showing the first eight; more decompositions exist.
