Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738208, here are decompositions:

7 + 8738201 = 8738208
47 + 8738161 = 8738208
79 + 8738129 = 8738208
107 + 8738101 = 8738208
137 + 8738071 = 8738208
197 + 8738011 = 8738208
229 + 8737979 = 8738208
337 + 8737871 = 8738208

Showing the first eight; more decompositions exist.
