Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011220, here are decompositions:

3 + 1011217 = 1011220
29 + 1011191 = 1011220
53 + 1011167 = 1011220
83 + 1011137 = 1011220
113 + 1011107 = 1011220
149 + 1011071 = 1011220
191 + 1011029 = 1011220
227 + 1010993 = 1011220

Showing the first eight; more decompositions exist.
