Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180422, here are decompositions:

3 + 180419 = 180422
31 + 180391 = 180422
43 + 180379 = 180422
61 + 180361 = 180422
163 + 180259 = 180422
181 + 180241 = 180422
211 + 180211 = 180422
241 + 180181 = 180422

Showing the first eight; more decompositions exist.
