Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642058, here are decompositions:

31 + 8642027 = 8642058
67 + 8641991 = 8642058
71 + 8641987 = 8642058
101 + 8641957 = 8642058
109 + 8641949 = 8642058
149 + 8641909 = 8642058
167 + 8641891 = 8642058
239 + 8641819 = 8642058

Showing the first eight; more decompositions exist.
