Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729148, here are decompositions:

7 + 8729141 = 8729148
17 + 8729131 = 8729148
31 + 8729117 = 8729148
41 + 8729107 = 8729148
67 + 8729081 = 8729148
89 + 8729059 = 8729148
97 + 8729051 = 8729148
179 + 8728969 = 8729148

Showing the first eight; more decompositions exist.
