Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181232, here are decompositions:

13 + 181219 = 181232
19 + 181213 = 181232
31 + 181201 = 181232
109 + 181123 = 181232
151 + 181081 = 181232
193 + 181039 = 181232
229 + 181003 = 181232
283 + 180949 = 181232

Showing the first eight; more decompositions exist.
