Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687228, here are decompositions:

19 + 8687209 = 8687228
31 + 8687197 = 8687228
79 + 8687149 = 8687228
97 + 8687131 = 8687228
139 + 8687089 = 8687228
229 + 8686999 = 8687228
421 + 8686807 = 8687228
499 + 8686729 = 8687228

Showing the first eight; more decompositions exist.
