Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728734, here are decompositions:

13 + 8728721 = 8728734
17 + 8728717 = 8728734
23 + 8728711 = 8728734
43 + 8728691 = 8728734
71 + 8728663 = 8728734
107 + 8728627 = 8728734
127 + 8728607 = 8728734
137 + 8728597 = 8728734

Showing the first eight; more decompositions exist.
