Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672220, here are decompositions:

13 + 8672207 = 8672220
17 + 8672203 = 8672220
19 + 8672201 = 8672220
43 + 8672177 = 8672220
59 + 8672161 = 8672220
103 + 8672117 = 8672220
157 + 8672063 = 8672220
173 + 8672047 = 8672220

Showing the first eight; more decompositions exist.
