Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727772, here are decompositions:

5 + 8727767 = 8727772
41 + 8727731 = 8727772
71 + 8727701 = 8727772
83 + 8727689 = 8727772
113 + 8727659 = 8727772
149 + 8727623 = 8727772
173 + 8727599 = 8727772
233 + 8727539 = 8727772

Showing the first eight; more decompositions exist.
