Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751444, here are decompositions:

5 + 8751439 = 8751444
17 + 8751427 = 8751444
43 + 8751401 = 8751444
73 + 8751371 = 8751444
103 + 8751341 = 8751444
193 + 8751251 = 8751444
211 + 8751233 = 8751444
223 + 8751221 = 8751444

Showing the first eight; more decompositions exist.
