Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997208, here are decompositions:

7 + 997201 = 997208
61 + 997147 = 997208
67 + 997141 = 997208
97 + 997111 = 997208
109 + 997099 = 997208
127 + 997081 = 997208
139 + 997069 = 997208
151 + 997057 = 997208

Showing the first eight; more decompositions exist.
