Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642018, here are decompositions:

31 + 8641987 = 8642018
61 + 8641957 = 8642018
109 + 8641909 = 8642018
127 + 8641891 = 8642018
199 + 8641819 = 8642018
211 + 8641807 = 8642018
271 + 8641747 = 8642018
277 + 8641741 = 8642018

Showing the first eight; more decompositions exist.
