Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658198, here are decompositions:

5 + 8658193 = 8658198
37 + 8658161 = 8658198
61 + 8658137 = 8658198
89 + 8658109 = 8658198
97 + 8658101 = 8658198
139 + 8658059 = 8658198
181 + 8658017 = 8658198
229 + 8657969 = 8658198

Showing the first eight; more decompositions exist.
