Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178984, here are decompositions:

11 + 178973 = 178984
53 + 178931 = 178984
107 + 178877 = 178984
131 + 178853 = 178984
167 + 178817 = 178984
191 + 178793 = 178984
227 + 178757 = 178984
293 + 178691 = 178984

Showing the first eight; more decompositions exist.
