Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729136, here are decompositions:

5 + 8729131 = 8729136
19 + 8729117 = 8729136
29 + 8729107 = 8729136
37 + 8729099 = 8729136
43 + 8729093 = 8729136
79 + 8729057 = 8729136
83 + 8729053 = 8729136
103 + 8729033 = 8729136

Showing the first eight; more decompositions exist.
