Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744140, here are decompositions:

11 + 8744129 = 8744140
59 + 8744081 = 8744140
107 + 8744033 = 8744140
137 + 8744003 = 8744140
149 + 8743991 = 8744140
227 + 8743913 = 8744140
239 + 8743901 = 8744140
257 + 8743883 = 8744140

Showing the first eight; more decompositions exist.
