Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044220, here are decompositions:

3 + 1044217 = 1044220
11 + 1044209 = 1044220
41 + 1044179 = 1044220
53 + 1044167 = 1044220
59 + 1044161 = 1044220
71 + 1044149 = 1044220
167 + 1044053 = 1044220
179 + 1044041 = 1044220

Showing the first eight; more decompositions exist.
