Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178948, here are decompositions:

17 + 178931 = 178948
41 + 178907 = 178948
59 + 178889 = 178948
71 + 178877 = 178948
89 + 178859 = 178948
131 + 178817 = 178948
149 + 178799 = 178948
167 + 178781 = 178948

Showing the first eight; more decompositions exist.
