Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143178, here are decompositions:

19 + 143159 = 143178
37 + 143141 = 143178
41 + 143137 = 143178
67 + 143111 = 143178
71 + 143107 = 143178
197 + 142981 = 143178
199 + 142979 = 143178
229 + 142949 = 143178

Showing the first eight; more decompositions exist.
