Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180282, here are decompositions:

19 + 180263 = 180282
23 + 180259 = 180282
41 + 180241 = 180282
43 + 180239 = 180282
61 + 180221 = 180282
71 + 180211 = 180282
101 + 180181 = 180282
103 + 180179 = 180282

Showing the first eight; more decompositions exist.
