Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143862, here are decompositions:

29 + 143833 = 143862
31 + 143831 = 143862
41 + 143821 = 143862
71 + 143791 = 143862
83 + 143779 = 143862
151 + 143711 = 143862
163 + 143699 = 143862
193 + 143669 = 143862

Showing the first eight; more decompositions exist.
