Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143298, here are decompositions:

7 + 143291 = 143298
11 + 143287 = 143298
17 + 143281 = 143298
37 + 143261 = 143298
41 + 143257 = 143298
59 + 143239 = 143298
101 + 143197 = 143298
139 + 143159 = 143298

Showing the first eight; more decompositions exist.
