Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997136, here are decompositions:

13 + 997123 = 997136
37 + 997099 = 997136
67 + 997069 = 997136
79 + 997057 = 997136
157 + 996979 = 997136
163 + 996973 = 997136
277 + 996859 = 997136
373 + 996763 = 997136

Showing the first eight; more decompositions exist.
