Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729238, here are decompositions:

17 + 8729221 = 8729238
19 + 8729219 = 8729238
31 + 8729207 = 8729238
47 + 8729191 = 8729238
59 + 8729179 = 8729238
97 + 8729141 = 8729238
107 + 8729131 = 8729238
131 + 8729107 = 8729238

Showing the first eight; more decompositions exist.
