Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178626, here are decompositions:

5 + 178621 = 178626
13 + 178613 = 178626
17 + 178609 = 178626
23 + 178603 = 178626
29 + 178597 = 178626
59 + 178567 = 178626
67 + 178559 = 178626
89 + 178537 = 178626

Showing the first eight; more decompositions exist.
