Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721114, here are decompositions:

13 + 8721101 = 8721114
37 + 8721077 = 8721114
53 + 8721061 = 8721114
71 + 8721043 = 8721114
137 + 8720977 = 8721114
167 + 8720947 = 8721114
173 + 8720941 = 8721114
223 + 8720891 = 8721114

Showing the first eight; more decompositions exist.
