Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729286, here are decompositions:

37 + 8729249 = 8729286
43 + 8729243 = 8729286
47 + 8729239 = 8729286
67 + 8729219 = 8729286
79 + 8729207 = 8729286
103 + 8729183 = 8729286
107 + 8729179 = 8729286
113 + 8729173 = 8729286

Showing the first eight; more decompositions exist.
