Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19598, here are decompositions:

67 + 19531 = 19598
97 + 19501 = 19598
109 + 19489 = 19598
127 + 19471 = 19598
151 + 19447 = 19598
157 + 19441 = 19598
181 + 19417 = 19598
211 + 19387 = 19598

Showing the first eight; more decompositions exist.
