Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738230, here are decompositions:

3 + 8738227 = 8738230
29 + 8738201 = 8738230
101 + 8738129 = 8738230
107 + 8738123 = 8738230
197 + 8738033 = 8738230
251 + 8737979 = 8738230
359 + 8737871 = 8738230
401 + 8737829 = 8738230

Showing the first eight; more decompositions exist.
