Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180356, here are decompositions:

19 + 180337 = 180356
67 + 180289 = 180356
97 + 180259 = 180356
109 + 180247 = 180356
283 + 180073 = 180356
313 + 180043 = 180356
349 + 180007 = 180356
367 + 179989 = 180356

Showing the first eight; more decompositions exist.
