Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727242, here are decompositions:

31 + 8727211 = 8727242
79 + 8727163 = 8727242
151 + 8727091 = 8727242
193 + 8727049 = 8727242
211 + 8727031 = 8727242
379 + 8726863 = 8727242
439 + 8726803 = 8727242
571 + 8726671 = 8727242

Showing the first eight; more decompositions exist.
