Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729480, here are decompositions:

13 + 8729467 = 8729480
79 + 8729401 = 8729480
157 + 8729323 = 8729480
163 + 8729317 = 8729480
241 + 8729239 = 8729480
307 + 8729173 = 8729480
349 + 8729131 = 8729480
373 + 8729107 = 8729480

Showing the first eight; more decompositions exist.
