Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725298, here are decompositions:

19 + 8725279 = 8725298
79 + 8725219 = 8725298
139 + 8725159 = 8725298
151 + 8725147 = 8725298
157 + 8725141 = 8725298
199 + 8725099 = 8725298
277 + 8725021 = 8725298
331 + 8724967 = 8725298

Showing the first eight; more decompositions exist.
