Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997946, here are decompositions:

13 + 997933 = 997946
67 + 997879 = 997946
139 + 997807 = 997946
163 + 997783 = 997946
283 + 997663 = 997946
337 + 997609 = 997946
349 + 997597 = 997946
373 + 997573 = 997946

Showing the first eight; more decompositions exist.
