Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048220, here are decompositions:

3 + 1048217 = 1048220
7 + 1048213 = 1048220
31 + 1048189 = 1048220
97 + 1048123 = 1048220
157 + 1048063 = 1048220
193 + 1048027 = 1048220
211 + 1048009 = 1048220
223 + 1047997 = 1048220

Showing the first eight; more decompositions exist.
