Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997156, here are decompositions:

3 + 997153 = 997156
5 + 997151 = 997156
47 + 997109 = 997156
53 + 997103 = 997156
59 + 997097 = 997156
113 + 997043 = 997156
137 + 997019 = 997156
257 + 996899 = 997156

Showing the first eight; more decompositions exist.
