Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173278, here are decompositions:

5 + 173273 = 173278
11 + 173267 = 173278
29 + 173249 = 173278
59 + 173219 = 173278
71 + 173207 = 173278
89 + 173189 = 173278
101 + 173177 = 173278
137 + 173141 = 173278

Showing the first eight; more decompositions exist.
