Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738210, here are decompositions:

109 + 8738101 = 8738210
127 + 8738083 = 8738210
139 + 8738071 = 8738210
157 + 8738053 = 8738210
163 + 8738047 = 8738210
199 + 8738011 = 8738210
277 + 8737933 = 8738210
337 + 8737873 = 8738210

Showing the first eight; more decompositions exist.
