Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727842, here are decompositions:

199 + 8727643 = 8727842
223 + 8727619 = 8727842
241 + 8727601 = 8727842
313 + 8727529 = 8727842
349 + 8727493 = 8727842
499 + 8727343 = 8727842
631 + 8727211 = 8727842
733 + 8727109 = 8727842

Showing the first eight; more decompositions exist.
