Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997536, here are decompositions:

73 + 997463 = 997536
83 + 997453 = 997536
97 + 997439 = 997536
103 + 997433 = 997536
109 + 997427 = 997536
157 + 997379 = 997536
167 + 997369 = 997536
179 + 997357 = 997536

Showing the first eight; more decompositions exist.
