Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729246, here are decompositions:

3 + 8729243 = 8729246
7 + 8729239 = 8729246
67 + 8729179 = 8729246
73 + 8729173 = 8729246
139 + 8729107 = 8729246
193 + 8729053 = 8729246
277 + 8728969 = 8729246
283 + 8728963 = 8729246

Showing the first eight; more decompositions exist.
