Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180528, here are decompositions:

17 + 180511 = 180528
31 + 180497 = 180528
37 + 180491 = 180528
109 + 180419 = 180528
137 + 180391 = 180528
149 + 180379 = 180528
157 + 180371 = 180528
167 + 180361 = 180528

Showing the first eight; more decompositions exist.
