Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749444, here are decompositions:

5 + 8749439 = 8749444
23 + 8749421 = 8749444
101 + 8749343 = 8749444
107 + 8749337 = 8749444
113 + 8749331 = 8749444
281 + 8749163 = 8749444
293 + 8749151 = 8749444
311 + 8749133 = 8749444

Showing the first eight; more decompositions exist.
