Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997250, here are decompositions:

3 + 997247 = 997250
31 + 997219 = 997250
43 + 997207 = 997250
97 + 997153 = 997250
103 + 997147 = 997250
109 + 997141 = 997250
127 + 997123 = 997250
139 + 997111 = 997250

Showing the first eight; more decompositions exist.
