Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726940, here are decompositions:

17 + 8726923 = 8726940
23 + 8726917 = 8726940
67 + 8726873 = 8726940
137 + 8726803 = 8726940
139 + 8726801 = 8726940
151 + 8726789 = 8726940
163 + 8726777 = 8726940
179 + 8726761 = 8726940

Showing the first eight; more decompositions exist.
