Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162212, here are decompositions:

3 + 162209 = 162212
103 + 162109 = 162212
229 + 161983 = 162212
241 + 161971 = 162212
331 + 161881 = 162212
373 + 161839 = 162212
433 + 161779 = 162212
439 + 161773 = 162212

Showing the first eight; more decompositions exist.
