Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749446, here are decompositions:

7 + 8749439 = 8749446
23 + 8749423 = 8749446
29 + 8749417 = 8749446
89 + 8749357 = 8749446
103 + 8749343 = 8749446
109 + 8749337 = 8749446
137 + 8749309 = 8749446
227 + 8749219 = 8749446

Showing the first eight; more decompositions exist.
