Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997670, here are decompositions:

7 + 997663 = 997670
19 + 997651 = 997670
43 + 997627 = 997670
61 + 997609 = 997670
73 + 997597 = 997670
97 + 997573 = 997670
313 + 997357 = 997670
337 + 997333 = 997670

Showing the first eight; more decompositions exist.
