Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056220, here are decompositions:

3 + 1056217 = 1056220
17 + 1056203 = 1056220
41 + 1056179 = 1056220
47 + 1056173 = 1056220
59 + 1056161 = 1056220
71 + 1056149 = 1056220
107 + 1056113 = 1056220
131 + 1056089 = 1056220

Showing the first eight; more decompositions exist.
