Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043220, here are decompositions:

7 + 1043213 = 1043220
11 + 1043209 = 1043220
19 + 1043201 = 1043220
29 + 1043191 = 1043220
37 + 1043183 = 1043220
43 + 1043177 = 1043220
47 + 1043173 = 1043220
53 + 1043167 = 1043220

Showing the first eight; more decompositions exist.
