Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642360, here are decompositions:

31 + 8642329 = 8642360
79 + 8642281 = 8642360
163 + 8642197 = 8642360
241 + 8642119 = 8642360
283 + 8642077 = 8642360
373 + 8641987 = 8642360
487 + 8641873 = 8642360
541 + 8641819 = 8642360

Showing the first eight; more decompositions exist.
