Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180498, here are decompositions:

7 + 180491 = 180498
61 + 180437 = 180498
79 + 180419 = 180498
107 + 180391 = 180498
127 + 180371 = 180498
137 + 180361 = 180498
151 + 180347 = 180498
167 + 180331 = 180498

Showing the first eight; more decompositions exist.
