Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640350, here are decompositions:

13 + 8640337 = 8640350
109 + 8640241 = 8640350
139 + 8640211 = 8640350
163 + 8640187 = 8640350
181 + 8640169 = 8640350
241 + 8640109 = 8640350
337 + 8640013 = 8640350
349 + 8640001 = 8640350

Showing the first eight; more decompositions exist.
