Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180468, here are decompositions:

5 + 180463 = 180468
31 + 180437 = 180468
89 + 180379 = 180468
97 + 180371 = 180468
107 + 180361 = 180468
131 + 180337 = 180468
137 + 180331 = 180468
151 + 180317 = 180468

Showing the first eight; more decompositions exist.
