Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997512, here are decompositions:

59 + 997453 = 997512
73 + 997439 = 997512
79 + 997433 = 997512
179 + 997333 = 997512
193 + 997319 = 997512
233 + 997279 = 997512
239 + 997273 = 997512
293 + 997219 = 997512

Showing the first eight; more decompositions exist.
