Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729456, here are decompositions:

67 + 8729389 = 8729456
139 + 8729317 = 8729456
277 + 8729179 = 8729456
283 + 8729173 = 8729456
349 + 8729107 = 8729456
397 + 8729059 = 8729456
487 + 8728969 = 8729456
607 + 8728849 = 8729456

Showing the first eight; more decompositions exist.
