Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143160, here are decompositions:

19 + 143141 = 143160
23 + 143137 = 143160
47 + 143113 = 143160
53 + 143107 = 143160
67 + 143093 = 143160
97 + 143063 = 143160
107 + 143053 = 143160
167 + 142993 = 143160

Showing the first eight; more decompositions exist.
