Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997378, here are decompositions:

59 + 997319 = 997378
71 + 997307 = 997378
131 + 997247 = 997378
227 + 997151 = 997378
257 + 997121 = 997378
269 + 997109 = 997378
281 + 997097 = 997378
359 + 997019 = 997378

Showing the first eight; more decompositions exist.
