Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143286, here are decompositions:

5 + 143281 = 143286
23 + 143263 = 143286
29 + 143257 = 143286
37 + 143249 = 143286
43 + 143243 = 143286
47 + 143239 = 143286
89 + 143197 = 143286
109 + 143177 = 143286

Showing the first eight; more decompositions exist.
