Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747440, here are decompositions:

17 + 8747423 = 8747440
59 + 8747381 = 8747440
113 + 8747327 = 8747440
167 + 8747273 = 8747440
179 + 8747261 = 8747440
197 + 8747243 = 8747440
227 + 8747213 = 8747440
269 + 8747171 = 8747440

Showing the first eight; more decompositions exist.
