Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727222, here are decompositions:

11 + 8727211 = 8727222
43 + 8727179 = 8727222
59 + 8727163 = 8727222
61 + 8727161 = 8727222
73 + 8727149 = 8727222
103 + 8727119 = 8727222
109 + 8727113 = 8727222
113 + 8727109 = 8727222

Showing the first eight; more decompositions exist.
