Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143328, here are decompositions:

37 + 143291 = 143328
41 + 143287 = 143328
47 + 143281 = 143328
67 + 143261 = 143328
71 + 143257 = 143328
79 + 143249 = 143328
89 + 143239 = 143328
131 + 143197 = 143328

Showing the first eight; more decompositions exist.
