Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997218, here are decompositions:

11 + 997207 = 997218
17 + 997201 = 997218
67 + 997151 = 997218
71 + 997147 = 997218
97 + 997121 = 997218
107 + 997111 = 997218
109 + 997109 = 997218
127 + 997091 = 997218

Showing the first eight; more decompositions exist.
