Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729268, here are decompositions:

19 + 8729249 = 8729268
29 + 8729239 = 8729268
47 + 8729221 = 8729268
61 + 8729207 = 8729268
89 + 8729179 = 8729268
127 + 8729141 = 8729268
137 + 8729131 = 8729268
151 + 8729117 = 8729268

Showing the first eight; more decompositions exist.
