Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729206, here are decompositions:

23 + 8729183 = 8729206
89 + 8729117 = 8729206
107 + 8729099 = 8729206
113 + 8729093 = 8729206
149 + 8729057 = 8729206
173 + 8729033 = 8729206
263 + 8728943 = 8729206
383 + 8728823 = 8729206

Showing the first eight; more decompositions exist.
