Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997224, here are decompositions:

5 + 997219 = 997224
17 + 997207 = 997224
23 + 997201 = 997224
61 + 997163 = 997224
71 + 997153 = 997224
73 + 997151 = 997224
83 + 997141 = 997224
101 + 997123 = 997224

Showing the first eight; more decompositions exist.
