Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997758, here are decompositions:

7 + 997751 = 997758
17 + 997741 = 997758
19 + 997739 = 997758
31 + 997727 = 997758
59 + 997699 = 997758
107 + 997651 = 997758
109 + 997649 = 997758
131 + 997627 = 997758

Showing the first eight; more decompositions exist.
