Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143252, here are decompositions:

3 + 143249 = 143252
13 + 143239 = 143252
139 + 143113 = 143252
199 + 143053 = 143252
271 + 142981 = 143252
283 + 142969 = 143252
313 + 142939 = 143252
349 + 142903 = 143252

Showing the first eight; more decompositions exist.
