Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662218, here are decompositions:

17 + 8662201 = 8662218
29 + 8662189 = 8662218
31 + 8662187 = 8662218
41 + 8662177 = 8662218
67 + 8662151 = 8662218
109 + 8662109 = 8662218
127 + 8662091 = 8662218
139 + 8662079 = 8662218

Showing the first eight; more decompositions exist.
