Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997718, here are decompositions:

19 + 997699 = 997718
37 + 997681 = 997718
67 + 997651 = 997718
109 + 997609 = 997718
349 + 997369 = 997718
409 + 997309 = 997718
439 + 997279 = 997718
499 + 997219 = 997718

Showing the first eight; more decompositions exist.
