Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997280, here are decompositions:

7 + 997273 = 997280
13 + 997267 = 997280
61 + 997219 = 997280
73 + 997207 = 997280
79 + 997201 = 997280
127 + 997153 = 997280
139 + 997141 = 997280
157 + 997123 = 997280

Showing the first eight; more decompositions exist.
