Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042212, here are decompositions:

19 + 1042193 = 1042212
29 + 1042183 = 1042212
71 + 1042141 = 1042212
79 + 1042133 = 1042212
89 + 1042123 = 1042212
103 + 1042109 = 1042212
109 + 1042103 = 1042212
113 + 1042099 = 1042212

Showing the first eight; more decompositions exist.
