Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162230, here are decompositions:

139 + 162091 = 162230
151 + 162079 = 162230
223 + 162007 = 162230
283 + 161947 = 162230
307 + 161923 = 162230
349 + 161881 = 162230
457 + 161773 = 162230
487 + 161743 = 162230

Showing the first eight; more decompositions exist.
