Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738028, here are decompositions:

17 + 8738011 = 8738028
107 + 8737921 = 8738028
157 + 8737871 = 8738028
179 + 8737849 = 8738028
199 + 8737829 = 8738028
227 + 8737801 = 8738028
239 + 8737789 = 8738028
311 + 8737717 = 8738028

Showing the first eight; more decompositions exist.
