Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729474, here are decompositions:

7 + 8729467 = 8729474
73 + 8729401 = 8729474
151 + 8729323 = 8729474
157 + 8729317 = 8729474
283 + 8729191 = 8729474
367 + 8729107 = 8729474
421 + 8729053 = 8729474
487 + 8728987 = 8729474

Showing the first eight; more decompositions exist.
