Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178996, here are decompositions:

23 + 178973 = 178996
89 + 178907 = 178996
107 + 178889 = 178996
137 + 178859 = 178996
179 + 178817 = 178996
197 + 178799 = 178996
239 + 178757 = 178996
353 + 178643 = 178996

Showing the first eight; more decompositions exist.
