Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143028, here are decompositions:

47 + 142981 = 143028
59 + 142969 = 143028
79 + 142949 = 143028
89 + 142939 = 143028
131 + 142897 = 143028
157 + 142871 = 143028
191 + 142837 = 143028
229 + 142799 = 143028

Showing the first eight; more decompositions exist.
