Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997598, here are decompositions:

229 + 997369 = 997598
241 + 997357 = 997598
271 + 997327 = 997598
331 + 997267 = 997598
379 + 997219 = 997598
397 + 997201 = 997598
457 + 997141 = 997598
487 + 997111 = 997598

Showing the first eight; more decompositions exist.
