Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721150, here are decompositions:

29 + 8721121 = 8721150
71 + 8721079 = 8721150
73 + 8721077 = 8721150
89 + 8721061 = 8721150
101 + 8721049 = 8721150
107 + 8721043 = 8721150
173 + 8720977 = 8721150
181 + 8720969 = 8721150

Showing the first eight; more decompositions exist.
