Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729178, here are decompositions:

5 + 8729173 = 8729178
37 + 8729141 = 8729178
47 + 8729131 = 8729178
61 + 8729117 = 8729178
71 + 8729107 = 8729178
79 + 8729099 = 8729178
97 + 8729081 = 8729178
127 + 8729051 = 8729178

Showing the first eight; more decompositions exist.
