Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738648, here are decompositions:

7 + 8738641 = 8738648
67 + 8738581 = 8738648
109 + 8738539 = 8738648
157 + 8738491 = 8738648
199 + 8738449 = 8738648
211 + 8738437 = 8738648
241 + 8738407 = 8738648
271 + 8738377 = 8738648

Showing the first eight; more decompositions exist.
