Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744538, here are decompositions:

31 + 8744507 = 8744538
41 + 8744497 = 8744538
71 + 8744467 = 8744538
79 + 8744459 = 8744538
241 + 8744297 = 8744538
269 + 8744269 = 8744538
277 + 8744261 = 8744538
311 + 8744227 = 8744538

Showing the first eight; more decompositions exist.
