Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715100, here are decompositions:

41 + 8715059 = 8715100
59 + 8715041 = 8715100
71 + 8715029 = 8715100
89 + 8715011 = 8715100
137 + 8714963 = 8715100
179 + 8714921 = 8715100
197 + 8714903 = 8715100
227 + 8714873 = 8715100

Showing the first eight; more decompositions exist.
