Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180412, here are decompositions:

41 + 180371 = 180412
101 + 180311 = 180412
131 + 180281 = 180412
149 + 180263 = 180412
173 + 180239 = 180412
179 + 180233 = 180412
191 + 180221 = 180412
233 + 180179 = 180412

Showing the first eight; more decompositions exist.
