Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640250, here are decompositions:

29 + 8640221 = 8640250
53 + 8640197 = 8640250
89 + 8640161 = 8640250
191 + 8640059 = 8640250
233 + 8640017 = 8640250
263 + 8639987 = 8640250
347 + 8639903 = 8640250
401 + 8639849 = 8640250

Showing the first eight; more decompositions exist.
