Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997212, here are decompositions:

5 + 997207 = 997212
11 + 997201 = 997212
59 + 997153 = 997212
61 + 997151 = 997212
71 + 997141 = 997212
89 + 997123 = 997212
101 + 997111 = 997212
103 + 997109 = 997212

Showing the first eight; more decompositions exist.
