Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642198, here are decompositions:

79 + 8642119 = 8642198
139 + 8642059 = 8642198
211 + 8641987 = 8642198
241 + 8641957 = 8642198
307 + 8641891 = 8642198
379 + 8641819 = 8642198
457 + 8641741 = 8642198
547 + 8641651 = 8642198

Showing the first eight; more decompositions exist.
