Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180236, here are decompositions:

3 + 180233 = 180236
139 + 180097 = 180236
163 + 180073 = 180236
193 + 180043 = 180236
229 + 180007 = 180236
283 + 179953 = 180236
313 + 179923 = 180236
337 + 179899 = 180236

Showing the first eight; more decompositions exist.
