Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143874, here are decompositions:

41 + 143833 = 143874
43 + 143831 = 143874
47 + 143827 = 143874
53 + 143821 = 143874
61 + 143813 = 143874
67 + 143807 = 143874
83 + 143791 = 143874
131 + 143743 = 143874

Showing the first eight; more decompositions exist.
