Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180598, here are decompositions:

29 + 180569 = 180598
59 + 180539 = 180598
101 + 180497 = 180598
107 + 180491 = 180598
179 + 180419 = 180598
227 + 180371 = 180598
251 + 180347 = 180598
281 + 180317 = 180598

Showing the first eight; more decompositions exist.
