Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997216, here are decompositions:

53 + 997163 = 997216
107 + 997109 = 997216
113 + 997103 = 997216
173 + 997043 = 997216
179 + 997037 = 997216
197 + 997019 = 997216
263 + 996953 = 997216
317 + 996899 = 997216

Showing the first eight; more decompositions exist.
