Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143850, here are decompositions:

17 + 143833 = 143850
19 + 143831 = 143850
23 + 143827 = 143850
29 + 143821 = 143850
37 + 143813 = 143850
43 + 143807 = 143850
53 + 143797 = 143850
59 + 143791 = 143850

Showing the first eight; more decompositions exist.
