Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997146, here are decompositions:

5 + 997141 = 997146
23 + 997123 = 997146
37 + 997109 = 997146
43 + 997103 = 997146
47 + 997099 = 997146
89 + 997057 = 997146
103 + 997043 = 997146
109 + 997037 = 997146

Showing the first eight; more decompositions exist.
