Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727828, here are decompositions:

19 + 8727809 = 8727828
37 + 8727791 = 8727828
61 + 8727767 = 8727828
71 + 8727757 = 8727828
97 + 8727731 = 8727828
101 + 8727727 = 8727828
127 + 8727701 = 8727828
139 + 8727689 = 8727828

Showing the first eight; more decompositions exist.
