Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28598, here are decompositions:

7 + 28591 = 28598
19 + 28579 = 28598
61 + 28537 = 28598
151 + 28447 = 28598
211 + 28387 = 28598
379 + 28219 = 28598
397 + 28201 = 28598
487 + 28111 = 28598

Showing the first eight; more decompositions exist.
