Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744824, here are decompositions:

5 + 8744819 = 8744824
107 + 8744717 = 8744824
113 + 8744711 = 8744824
197 + 8744627 = 8744824
311 + 8744513 = 8744824
317 + 8744507 = 8744824
401 + 8744423 = 8744824
563 + 8744261 = 8744824

Showing the first eight; more decompositions exist.
