Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747208, here are decompositions:

17 + 8747191 = 8747208
37 + 8747171 = 8747208
89 + 8747119 = 8747208
97 + 8747111 = 8747208
137 + 8747071 = 8747208
167 + 8747041 = 8747208
229 + 8746979 = 8747208
241 + 8746967 = 8747208

Showing the first eight; more decompositions exist.
