Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744278, here are decompositions:

17 + 8744261 = 8744278
71 + 8744207 = 8744278
89 + 8744189 = 8744278
149 + 8744129 = 8744278
197 + 8744081 = 8744278
281 + 8743997 = 8744278
359 + 8743919 = 8744278
461 + 8743817 = 8744278

Showing the first eight; more decompositions exist.
