Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143142, here are decompositions:

5 + 143137 = 143142
29 + 143113 = 143142
31 + 143111 = 143142
79 + 143063 = 143142
89 + 143053 = 143142
149 + 142993 = 143142
163 + 142979 = 143142
173 + 142969 = 143142

Showing the first eight; more decompositions exist.
