Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729528, here are decompositions:

37 + 8729491 = 8729528
61 + 8729467 = 8729528
127 + 8729401 = 8729528
139 + 8729389 = 8729528
211 + 8729317 = 8729528
307 + 8729221 = 8729528
337 + 8729191 = 8729528
349 + 8729179 = 8729528

Showing the first eight; more decompositions exist.
