Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997616, here are decompositions:

7 + 997609 = 997616
19 + 997597 = 997616
43 + 997573 = 997616
163 + 997453 = 997616
283 + 997333 = 997616
307 + 997309 = 997616
337 + 997279 = 997616
349 + 997267 = 997616

Showing the first eight; more decompositions exist.
