Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178662, here are decompositions:

19 + 178643 = 178662
23 + 178639 = 178662
41 + 178621 = 178662
53 + 178609 = 178662
59 + 178603 = 178662
61 + 178601 = 178662
101 + 178561 = 178662
103 + 178559 = 178662

Showing the first eight; more decompositions exist.
