Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997144, here are decompositions:

3 + 997141 = 997144
23 + 997121 = 997144
41 + 997103 = 997144
47 + 997097 = 997144
53 + 997091 = 997144
101 + 997043 = 997144
107 + 997037 = 997144
131 + 997013 = 997144

Showing the first eight; more decompositions exist.
