Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997380, here are decompositions:

11 + 997369 = 997380
23 + 997357 = 997380
37 + 997343 = 997380
47 + 997333 = 997380
53 + 997327 = 997380
61 + 997319 = 997380
71 + 997309 = 997380
73 + 997307 = 997380

Showing the first eight; more decompositions exist.
