Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729588, here are decompositions:

31 + 8729557 = 8729588
97 + 8729491 = 8729588
199 + 8729389 = 8729588
271 + 8729317 = 8729588
349 + 8729239 = 8729588
367 + 8729221 = 8729588
397 + 8729191 = 8729588
409 + 8729179 = 8729588

Showing the first eight; more decompositions exist.
