Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717228, here are decompositions:

97 + 8717131 = 8717228
109 + 8717119 = 8717228
229 + 8716999 = 8717228
271 + 8716957 = 8717228
337 + 8716891 = 8717228
367 + 8716861 = 8717228
409 + 8716819 = 8717228
601 + 8716627 = 8717228

Showing the first eight; more decompositions exist.
