Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726886, here are decompositions:

13 + 8726873 = 8726886
23 + 8726863 = 8726886
37 + 8726849 = 8726886
83 + 8726803 = 8726886
97 + 8726789 = 8726886
109 + 8726777 = 8726886
127 + 8726759 = 8726886
149 + 8726737 = 8726886

Showing the first eight; more decompositions exist.
