Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744778, here are decompositions:

41 + 8744737 = 8744778
61 + 8744717 = 8744778
67 + 8744711 = 8744778
71 + 8744707 = 8744778
151 + 8744627 = 8744778
167 + 8744611 = 8744778
179 + 8744599 = 8744778
227 + 8744551 = 8744778

Showing the first eight; more decompositions exist.
