Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997400, here are decompositions:

31 + 997369 = 997400
43 + 997357 = 997400
67 + 997333 = 997400
73 + 997327 = 997400
127 + 997273 = 997400
181 + 997219 = 997400
193 + 997207 = 997400
199 + 997201 = 997400

Showing the first eight; more decompositions exist.
