Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738558, here are decompositions:

19 + 8738539 = 8738558
67 + 8738491 = 8738558
109 + 8738449 = 8738558
151 + 8738407 = 8738558
181 + 8738377 = 8738558
277 + 8738281 = 8738558
331 + 8738227 = 8738558
349 + 8738209 = 8738558

Showing the first eight; more decompositions exist.
