Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721110, here are decompositions:

31 + 8721079 = 8721110
61 + 8721049 = 8721110
67 + 8721043 = 8721110
157 + 8720953 = 8721110
163 + 8720947 = 8721110
199 + 8720911 = 8721110
271 + 8720839 = 8721110
313 + 8720797 = 8721110

Showing the first eight; more decompositions exist.
