Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738288, here are decompositions:

7 + 8738281 = 8738288
61 + 8738227 = 8738288
79 + 8738209 = 8738288
127 + 8738161 = 8738288
199 + 8738089 = 8738288
241 + 8738047 = 8738288
277 + 8738011 = 8738288
367 + 8737921 = 8738288

Showing the first eight; more decompositions exist.
