Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997142, here are decompositions:

19 + 997123 = 997142
31 + 997111 = 997142
43 + 997099 = 997142
61 + 997081 = 997142
73 + 997069 = 997142
163 + 996979 = 997142
271 + 996871 = 997142
283 + 996859 = 997142

Showing the first eight; more decompositions exist.
