Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744440, here are decompositions:

17 + 8744423 = 8744440
179 + 8744261 = 8744440
197 + 8744243 = 8744440
233 + 8744207 = 8744440
251 + 8744189 = 8744440
311 + 8744129 = 8744440
359 + 8744081 = 8744440
443 + 8743997 = 8744440

Showing the first eight; more decompositions exist.
