Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709228, here are decompositions:

7 + 8709221 = 8709228
37 + 8709191 = 8709228
41 + 8709187 = 8709228
79 + 8709149 = 8709228
89 + 8709139 = 8709228
107 + 8709121 = 8709228
149 + 8709079 = 8709228
257 + 8708971 = 8709228

Showing the first eight; more decompositions exist.
