Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727740, here are decompositions:

13 + 8727727 = 8727740
67 + 8727673 = 8727740
97 + 8727643 = 8727740
139 + 8727601 = 8727740
157 + 8727583 = 8727740
163 + 8727577 = 8727740
211 + 8727529 = 8727740
313 + 8727427 = 8727740

Showing the first eight; more decompositions exist.
