Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997436, here are decompositions:

3 + 997433 = 997436
67 + 997369 = 997436
79 + 997357 = 997436
103 + 997333 = 997436
109 + 997327 = 997436
127 + 997309 = 997436
157 + 997279 = 997436
163 + 997273 = 997436

Showing the first eight; more decompositions exist.
