Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997300, here are decompositions:

41 + 997259 = 997300
53 + 997247 = 997300
137 + 997163 = 997300
149 + 997151 = 997300
179 + 997121 = 997300
191 + 997109 = 997300
197 + 997103 = 997300
257 + 997043 = 997300

Showing the first eight; more decompositions exist.
