Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729788, here are decompositions:

59 + 8729729 = 8729788
71 + 8729717 = 8729788
107 + 8729681 = 8729788
167 + 8729621 = 8729788
359 + 8729429 = 8729788
461 + 8729327 = 8729788
479 + 8729309 = 8729788
569 + 8729219 = 8729788

Showing the first eight; more decompositions exist.
