Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700208, here are decompositions:

47 + 8700161 = 8700208
137 + 8700071 = 8700208
149 + 8700059 = 8700208
197 + 8700011 = 8700208
227 + 8699981 = 8700208
239 + 8699969 = 8700208
401 + 8699807 = 8700208
641 + 8699567 = 8700208

Showing the first eight; more decompositions exist.
