Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729244, here are decompositions:

5 + 8729239 = 8729244
23 + 8729221 = 8729244
37 + 8729207 = 8729244
53 + 8729191 = 8729244
61 + 8729183 = 8729244
71 + 8729173 = 8729244
103 + 8729141 = 8729244
113 + 8729131 = 8729244

Showing the first eight; more decompositions exist.
