Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997340, here are decompositions:

7 + 997333 = 997340
13 + 997327 = 997340
31 + 997309 = 997340
61 + 997279 = 997340
67 + 997273 = 997340
73 + 997267 = 997340
139 + 997201 = 997340
193 + 997147 = 997340

Showing the first eight; more decompositions exist.
