Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677438, here are decompositions:

41 + 8677397 = 8677438
47 + 8677391 = 8677438
71 + 8677367 = 8677438
149 + 8677289 = 8677438
191 + 8677247 = 8677438
257 + 8677181 = 8677438
311 + 8677127 = 8677438
317 + 8677121 = 8677438

Showing the first eight; more decompositions exist.
