Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143268, here are decompositions:

5 + 143263 = 143268
7 + 143261 = 143268
11 + 143257 = 143268
19 + 143249 = 143268
29 + 143239 = 143268
71 + 143197 = 143268
109 + 143159 = 143268
127 + 143141 = 143268

Showing the first eight; more decompositions exist.
