Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942218, here are decompositions:

19 + 942199 = 942218
31 + 942187 = 942218
127 + 942091 = 942218
139 + 942079 = 942218
157 + 942061 = 942218
181 + 942037 = 942218
229 + 941989 = 942218
271 + 941947 = 942218

Showing the first eight; more decompositions exist.
