Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712728, here are decompositions:

19 + 8712709 = 8712728
67 + 8712661 = 8712728
127 + 8712601 = 8712728
151 + 8712577 = 8712728
181 + 8712547 = 8712728
307 + 8712421 = 8712728
331 + 8712397 = 8712728
379 + 8712349 = 8712728

Showing the first eight; more decompositions exist.
