Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747298, here are decompositions:

37 + 8747261 = 8747298
41 + 8747257 = 8747298
47 + 8747251 = 8747298
107 + 8747191 = 8747298
127 + 8747171 = 8747298
139 + 8747159 = 8747298
179 + 8747119 = 8747298
227 + 8747071 = 8747298

Showing the first eight; more decompositions exist.
