Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729008, here are decompositions:

107 + 8728901 = 8729008
251 + 8728757 = 8729008
317 + 8728691 = 8729008
359 + 8728649 = 8729008
401 + 8728607 = 8729008
677 + 8728331 = 8729008
719 + 8728289 = 8729008
797 + 8728211 = 8729008

Showing the first eight; more decompositions exist.
