Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744866, here are decompositions:

5 + 8744861 = 8744866
23 + 8744843 = 8744866
29 + 8744837 = 8744866
47 + 8744819 = 8744866
149 + 8744717 = 8744866
239 + 8744627 = 8744866
353 + 8744513 = 8744866
359 + 8744507 = 8744866

Showing the first eight; more decompositions exist.
