Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181482, here are decompositions:

23 + 181459 = 181482
43 + 181439 = 181482
61 + 181421 = 181482
73 + 181409 = 181482
83 + 181399 = 181482
179 + 181303 = 181482
181 + 181301 = 181482
199 + 181283 = 181482

Showing the first eight; more decompositions exist.
