Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727790, here are decompositions:

11 + 8727779 = 8727790
17 + 8727773 = 8727790
23 + 8727767 = 8727790
59 + 8727731 = 8727790
89 + 8727701 = 8727790
101 + 8727689 = 8727790
131 + 8727659 = 8727790
167 + 8727623 = 8727790

Showing the first eight; more decompositions exist.
