Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746220, here are decompositions:

13 + 8746207 = 8746220
103 + 8746117 = 8746220
127 + 8746093 = 8746220
151 + 8746069 = 8746220
157 + 8746063 = 8746220
211 + 8746009 = 8746220
229 + 8745991 = 8746220
331 + 8745889 = 8746220

Showing the first eight; more decompositions exist.
