Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748228, here are decompositions:

19 + 8748209 = 8748228
29 + 8748199 = 8748228
37 + 8748191 = 8748228
61 + 8748167 = 8748228
67 + 8748161 = 8748228
131 + 8748097 = 8748228
197 + 8748031 = 8748228
211 + 8748017 = 8748228

Showing the first eight; more decompositions exist.
