Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178902, here are decompositions:

5 + 178897 = 178902
13 + 178889 = 178902
29 + 178873 = 178902
43 + 178859 = 178902
71 + 178831 = 178902
83 + 178819 = 178902
89 + 178813 = 178902
103 + 178799 = 178902

Showing the first eight; more decompositions exist.
