Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020356, here are decompositions:

3 + 1020353 = 1020356
19 + 1020337 = 1020356
97 + 1020259 = 1020356
109 + 1020247 = 1020356
193 + 1020163 = 1020356
199 + 1020157 = 1020356
277 + 1020079 = 1020356
307 + 1020049 = 1020356

Showing the first eight; more decompositions exist.
