Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997190, here are decompositions:

37 + 997153 = 997190
43 + 997147 = 997190
67 + 997123 = 997190
79 + 997111 = 997190
109 + 997081 = 997190
211 + 996979 = 997190
223 + 996967 = 997190
307 + 996883 = 997190

Showing the first eight; more decompositions exist.
