Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744644, here are decompositions:

17 + 8744627 = 8744644
107 + 8744537 = 8744644
131 + 8744513 = 8744644
137 + 8744507 = 8744644
197 + 8744447 = 8744644
347 + 8744297 = 8744644
383 + 8744261 = 8744644
401 + 8744243 = 8744644

Showing the first eight; more decompositions exist.
