Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649444, here are decompositions:

53 + 8649391 = 8649444
61 + 8649383 = 8649444
73 + 8649371 = 8649444
101 + 8649343 = 8649444
113 + 8649331 = 8649444
127 + 8649317 = 8649444
151 + 8649293 = 8649444
191 + 8649253 = 8649444

Showing the first eight; more decompositions exist.
