Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744378, here are decompositions:

61 + 8744317 = 8744378
109 + 8744269 = 8744378
151 + 8744227 = 8744378
229 + 8744149 = 8744378
277 + 8744101 = 8744378
337 + 8744041 = 8744378
397 + 8743981 = 8744378
499 + 8743879 = 8744378

Showing the first eight; more decompositions exist.
