Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649392, here are decompositions:

43 + 8649349 = 8649392
61 + 8649331 = 8649392
109 + 8649283 = 8649392
139 + 8649253 = 8649392
151 + 8649241 = 8649392
181 + 8649211 = 8649392
313 + 8649079 = 8649392
331 + 8649061 = 8649392

Showing the first eight; more decompositions exist.
