Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143802, here are decompositions:

5 + 143797 = 143802
11 + 143791 = 143802
23 + 143779 = 143802
59 + 143743 = 143802
73 + 143729 = 143802
83 + 143719 = 143802
103 + 143699 = 143802
149 + 143653 = 143802

Showing the first eight; more decompositions exist.
