Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997406, here are decompositions:

37 + 997369 = 997406
73 + 997333 = 997406
79 + 997327 = 997406
97 + 997309 = 997406
127 + 997279 = 997406
139 + 997267 = 997406
199 + 997207 = 997406
283 + 997123 = 997406

Showing the first eight; more decompositions exist.
