Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729226, here are decompositions:

5 + 8729221 = 8729226
7 + 8729219 = 8729226
19 + 8729207 = 8729226
43 + 8729183 = 8729226
47 + 8729179 = 8729226
53 + 8729173 = 8729226
109 + 8729117 = 8729226
127 + 8729099 = 8729226

Showing the first eight; more decompositions exist.
