Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729558, here are decompositions:

67 + 8729491 = 8729558
157 + 8729401 = 8729558
241 + 8729317 = 8729558
337 + 8729221 = 8729558
367 + 8729191 = 8729558
379 + 8729179 = 8729558
499 + 8729059 = 8729558
571 + 8728987 = 8729558

Showing the first eight; more decompositions exist.
