Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997222, here are decompositions:

3 + 997219 = 997222
59 + 997163 = 997222
71 + 997151 = 997222
101 + 997121 = 997222
113 + 997109 = 997222
131 + 997091 = 997222
179 + 997043 = 997222
269 + 996953 = 997222

Showing the first eight; more decompositions exist.
