Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178888, here are decompositions:

11 + 178877 = 178888
29 + 178859 = 178888
71 + 178817 = 178888
89 + 178799 = 178888
107 + 178781 = 178888
131 + 178757 = 178888
191 + 178697 = 178888
197 + 178691 = 178888

Showing the first eight; more decompositions exist.
