Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756228, here are decompositions:

7 + 8756221 = 8756228
79 + 8756149 = 8756228
109 + 8756119 = 8756228
127 + 8756101 = 8756228
139 + 8756089 = 8756228
277 + 8755951 = 8756228
307 + 8755921 = 8756228
337 + 8755891 = 8756228

Showing the first eight; more decompositions exist.
