Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618198, here are decompositions:

67 + 8618131 = 8618198
79 + 8618119 = 8618198
109 + 8618089 = 8618198
139 + 8618059 = 8618198
151 + 8618047 = 8618198
157 + 8618041 = 8618198
271 + 8617927 = 8618198
499 + 8617699 = 8618198

Showing the first eight; more decompositions exist.
