Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180424, here are decompositions:

5 + 180419 = 180424
11 + 180413 = 180424
53 + 180371 = 180424
107 + 180317 = 180424
113 + 180311 = 180424
137 + 180287 = 180424
191 + 180233 = 180424
263 + 180161 = 180424

Showing the first eight; more decompositions exist.
