Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178716, here are decompositions:

19 + 178697 = 178716
23 + 178693 = 178716
73 + 178643 = 178716
89 + 178627 = 178716
103 + 178613 = 178716
107 + 178609 = 178716
113 + 178603 = 178716
149 + 178567 = 178716

Showing the first eight; more decompositions exist.
