Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997278, here are decompositions:

5 + 997273 = 997278
11 + 997267 = 997278
19 + 997259 = 997278
31 + 997247 = 997278
59 + 997219 = 997278
71 + 997207 = 997278
127 + 997151 = 997278
131 + 997147 = 997278

Showing the first eight; more decompositions exist.
