Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744430, here are decompositions:

7 + 8744423 = 8744430
11 + 8744419 = 8744430
17 + 8744413 = 8744430
113 + 8744317 = 8744430
197 + 8744233 = 8744430
223 + 8744207 = 8744430
239 + 8744191 = 8744430
241 + 8744189 = 8744430

Showing the first eight; more decompositions exist.
