Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729232, here are decompositions:

11 + 8729221 = 8729232
13 + 8729219 = 8729232
41 + 8729191 = 8729232
53 + 8729179 = 8729232
59 + 8729173 = 8729232
101 + 8729131 = 8729232
139 + 8729093 = 8729232
151 + 8729081 = 8729232

Showing the first eight; more decompositions exist.
