Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627398, here are decompositions:

41 + 8627357 = 8627398
47 + 8627351 = 8627398
251 + 8627147 = 8627398
257 + 8627141 = 8627398
317 + 8627081 = 8627398
347 + 8627051 = 8627398
557 + 8626841 = 8627398
587 + 8626811 = 8627398

Showing the first eight; more decompositions exist.
