Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997964, here are decompositions:

3 + 997961 = 997964
31 + 997933 = 997964
67 + 997897 = 997964
73 + 997891 = 997964
151 + 997813 = 997964
157 + 997807 = 997964
181 + 997783 = 997964
223 + 997741 = 997964

Showing the first eight; more decompositions exist.
