Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180342, here are decompositions:

5 + 180337 = 180342
11 + 180331 = 180342
31 + 180311 = 180342
53 + 180289 = 180342
61 + 180281 = 180342
79 + 180263 = 180342
83 + 180259 = 180342
101 + 180241 = 180342

Showing the first eight; more decompositions exist.
