Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744442, here are decompositions:

19 + 8744423 = 8744442
23 + 8744419 = 8744442
29 + 8744413 = 8744442
173 + 8744269 = 8744442
181 + 8744261 = 8744442
199 + 8744243 = 8744442
251 + 8744191 = 8744442
293 + 8744149 = 8744442

Showing the first eight; more decompositions exist.
