Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744238, here are decompositions:

5 + 8744233 = 8744238
11 + 8744227 = 8744238
31 + 8744207 = 8744238
47 + 8744191 = 8744238
89 + 8744149 = 8744238
109 + 8744129 = 8744238
137 + 8744101 = 8744238
157 + 8744081 = 8744238

Showing the first eight; more decompositions exist.
