Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997748, here are decompositions:

7 + 997741 = 997748
67 + 997681 = 997748
97 + 997651 = 997748
139 + 997609 = 997748
151 + 997597 = 997748
379 + 997369 = 997748
421 + 997327 = 997748
439 + 997309 = 997748

Showing the first eight; more decompositions exist.
