Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997210, here are decompositions:

3 + 997207 = 997210
47 + 997163 = 997210
59 + 997151 = 997210
89 + 997121 = 997210
101 + 997109 = 997210
107 + 997103 = 997210
113 + 997097 = 997210
167 + 997043 = 997210

Showing the first eight; more decompositions exist.
