Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649452, here are decompositions:

43 + 8649409 = 8649452
61 + 8649391 = 8649452
103 + 8649349 = 8649452
109 + 8649343 = 8649452
199 + 8649253 = 8649452
211 + 8649241 = 8649452
241 + 8649211 = 8649452
349 + 8649103 = 8649452

Showing the first eight; more decompositions exist.
