Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178758, here are decompositions:

5 + 178753 = 178758
61 + 178697 = 178758
67 + 178691 = 178758
131 + 178627 = 178758
137 + 178621 = 178758
149 + 178609 = 178758
157 + 178601 = 178758
191 + 178567 = 178758

Showing the first eight; more decompositions exist.
