Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178712, here are decompositions:

19 + 178693 = 178712
31 + 178681 = 178712
73 + 178639 = 178712
103 + 178609 = 178712
109 + 178603 = 178712
151 + 178561 = 178712
181 + 178531 = 178712
199 + 178513 = 178712

Showing the first eight; more decompositions exist.
