Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729236, here are decompositions:

17 + 8729219 = 8729236
29 + 8729207 = 8729236
53 + 8729183 = 8729236
137 + 8729099 = 8729236
179 + 8729057 = 8729236
293 + 8728943 = 8729236
353 + 8728883 = 8729236
449 + 8728787 = 8729236

Showing the first eight; more decompositions exist.
