Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997150, here are decompositions:

3 + 997147 = 997150
29 + 997121 = 997150
41 + 997109 = 997150
47 + 997103 = 997150
53 + 997097 = 997150
59 + 997091 = 997150
107 + 997043 = 997150
113 + 997037 = 997150

Showing the first eight; more decompositions exist.
