Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997994, here are decompositions:

3 + 997991 = 997994
31 + 997963 = 997994
61 + 997933 = 997994
97 + 997897 = 997994
103 + 997891 = 997994
181 + 997813 = 997994
211 + 997783 = 997994
313 + 997681 = 997994

Showing the first eight; more decompositions exist.
