Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997628, here are decompositions:

19 + 997609 = 997628
31 + 997597 = 997628
271 + 997357 = 997628
349 + 997279 = 997628
409 + 997219 = 997628
421 + 997207 = 997628
487 + 997141 = 997628
547 + 997081 = 997628

Showing the first eight; more decompositions exist.
