Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997188, here are decompositions:

37 + 997151 = 997188
41 + 997147 = 997188
47 + 997141 = 997188
67 + 997121 = 997188
79 + 997109 = 997188
89 + 997099 = 997188
97 + 997091 = 997188
107 + 997081 = 997188

Showing the first eight; more decompositions exist.
