Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726814, here are decompositions:

11 + 8726803 = 8726814
13 + 8726801 = 8726814
37 + 8726777 = 8726814
53 + 8726761 = 8726814
101 + 8726713 = 8726814
127 + 8726687 = 8726814
137 + 8726677 = 8726814
167 + 8726647 = 8726814

Showing the first eight; more decompositions exist.
