Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627428, here are decompositions:

11 + 8627417 = 8627428
71 + 8627357 = 8627428
107 + 8627321 = 8627428
281 + 8627147 = 8627428
317 + 8627111 = 8627428
347 + 8627081 = 8627428
587 + 8626841 = 8627428
617 + 8626811 = 8627428

Showing the first eight; more decompositions exist.
