Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738228, here are decompositions:

19 + 8738209 = 8738228
67 + 8738161 = 8738228
127 + 8738101 = 8738228
139 + 8738089 = 8738228
157 + 8738071 = 8738228
181 + 8738047 = 8738228
307 + 8737921 = 8738228
379 + 8737849 = 8738228

Showing the first eight; more decompositions exist.
