Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744540, here are decompositions:

3 + 8744537 = 8744540
43 + 8744497 = 8744540
73 + 8744467 = 8744540
127 + 8744413 = 8744540
223 + 8744317 = 8744540
271 + 8744269 = 8744540
307 + 8744233 = 8744540
313 + 8744227 = 8744540

Showing the first eight; more decompositions exist.
