Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997256, here are decompositions:

37 + 997219 = 997256
103 + 997153 = 997256
109 + 997147 = 997256
157 + 997099 = 997256
199 + 997057 = 997256
277 + 996979 = 997256
283 + 996973 = 997256
373 + 996883 = 997256

Showing the first eight; more decompositions exist.
