Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997182, here are decompositions:

19 + 997163 = 997182
29 + 997153 = 997182
31 + 997151 = 997182
41 + 997141 = 997182
59 + 997123 = 997182
61 + 997121 = 997182
71 + 997111 = 997182
73 + 997109 = 997182

Showing the first eight; more decompositions exist.
