Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727778, here are decompositions:

5 + 8727773 = 8727778
11 + 8727767 = 8727778
47 + 8727731 = 8727778
89 + 8727689 = 8727778
167 + 8727611 = 8727778
179 + 8727599 = 8727778
239 + 8727539 = 8727778
281 + 8727497 = 8727778

Showing the first eight; more decompositions exist.
