Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997982, here are decompositions:

19 + 997963 = 997982
103 + 997879 = 997982
199 + 997783 = 997982
241 + 997741 = 997982
283 + 997699 = 997982
331 + 997651 = 997982
373 + 997609 = 997982
409 + 997573 = 997982

Showing the first eight; more decompositions exist.
