Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108212, here are decompositions:

19 + 108193 = 108212
73 + 108139 = 108212
103 + 108109 = 108212
151 + 108061 = 108212
199 + 108013 = 108212
241 + 107971 = 108212
271 + 107941 = 108212
331 + 107881 = 108212

Showing the first eight; more decompositions exist.
