Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673228, here are decompositions:

7 + 8673221 = 8673228
19 + 8673209 = 8673228
29 + 8673199 = 8673228
41 + 8673187 = 8673228
61 + 8673167 = 8673228
71 + 8673157 = 8673228
97 + 8673131 = 8673228
101 + 8673127 = 8673228

Showing the first eight; more decompositions exist.
