Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729330, here are decompositions:

3 + 8729327 = 8729330
7 + 8729323 = 8729330
13 + 8729317 = 8729330
109 + 8729221 = 8729330
139 + 8729191 = 8729330
151 + 8729179 = 8729330
157 + 8729173 = 8729330
199 + 8729131 = 8729330

Showing the first eight; more decompositions exist.
