Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997700, here are decompositions:

7 + 997693 = 997700
19 + 997681 = 997700
37 + 997663 = 997700
73 + 997627 = 997700
103 + 997597 = 997700
127 + 997573 = 997700
331 + 997369 = 997700
367 + 997333 = 997700

Showing the first eight; more decompositions exist.
