Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727258, here are decompositions:

11 + 8727247 = 8727258
47 + 8727211 = 8727258
61 + 8727197 = 8727258
79 + 8727179 = 8727258
97 + 8727161 = 8727258
101 + 8727157 = 8727258
109 + 8727149 = 8727258
139 + 8727119 = 8727258

Showing the first eight; more decompositions exist.
