Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707100, here are decompositions:

7 + 8707093 = 8707100
43 + 8707057 = 8707100
79 + 8707021 = 8707100
97 + 8707003 = 8707100
139 + 8706961 = 8707100
163 + 8706937 = 8707100
229 + 8706871 = 8707100
271 + 8706829 = 8707100

Showing the first eight; more decompositions exist.
