Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738458, here are decompositions:

11 + 8738447 = 8738458
59 + 8738399 = 8738458
107 + 8738351 = 8738458
227 + 8738231 = 8738458
257 + 8738201 = 8738458
479 + 8737979 = 8738458
587 + 8737871 = 8738458
761 + 8737697 = 8738458

Showing the first eight; more decompositions exist.
