Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744426, here are decompositions:

3 + 8744423 = 8744426
7 + 8744419 = 8744426
13 + 8744413 = 8744426
109 + 8744317 = 8744426
157 + 8744269 = 8744426
193 + 8744233 = 8744426
199 + 8744227 = 8744426
277 + 8744149 = 8744426

Showing the first eight; more decompositions exist.
