Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744218, here are decompositions:

11 + 8744207 = 8744218
29 + 8744189 = 8744218
89 + 8744129 = 8744218
137 + 8744081 = 8744218
227 + 8743991 = 8744218
281 + 8743937 = 8744218
317 + 8743901 = 8744218
401 + 8743817 = 8744218

Showing the first eight; more decompositions exist.
