Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178146, here are decompositions:

5 + 178141 = 178146
19 + 178127 = 178146
29 + 178117 = 178146
43 + 178103 = 178146
53 + 178093 = 178146
79 + 178067 = 178146
107 + 178039 = 178146
109 + 178037 = 178146

Showing the first eight; more decompositions exist.
