Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744420, here are decompositions:

7 + 8744413 = 8744420
103 + 8744317 = 8744420
151 + 8744269 = 8744420
193 + 8744227 = 8744420
229 + 8744191 = 8744420
271 + 8744149 = 8744420
277 + 8744143 = 8744420
337 + 8744083 = 8744420

Showing the first eight; more decompositions exist.
