Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729522, here are decompositions:

31 + 8729491 = 8729522
199 + 8729323 = 8729522
283 + 8729239 = 8729522
331 + 8729191 = 8729522
349 + 8729173 = 8729522
463 + 8729059 = 8729522
601 + 8728921 = 8729522
619 + 8728903 = 8729522

Showing the first eight; more decompositions exist.
