Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744918, here are decompositions:

31 + 8744887 = 8744918
181 + 8744737 = 8744918
211 + 8744707 = 8744918
307 + 8744611 = 8744918
367 + 8744551 = 8744918
421 + 8744497 = 8744918
499 + 8744419 = 8744918
601 + 8744317 = 8744918

Showing the first eight; more decompositions exist.
