Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178610, here are decompositions:

7 + 178603 = 178610
13 + 178597 = 178610
43 + 178567 = 178610
73 + 178537 = 178610
79 + 178531 = 178610
97 + 178513 = 178610
109 + 178501 = 178610
163 + 178447 = 178610

Showing the first eight; more decompositions exist.
